First Look: “K-3000” from spankermachine.com
I randomly ran across this in a photo on FetLife some time a couple of weeks ago and impulse purchased one, they’re available from https://spankermachine.com.
This post will cover a first impression and some basic testing that I’ve done so far.
Out of the box there are some disappointments, the mounting hardware is definitely NOT stainless steel as claimed on their website. The upright is clearly a die-cast zinc alloy (much of the gravity of the package comes from this part), the arm is zinc plated steel, and the bracket is cast aluminium. Nothing actually *wrong* with those material choices, but I object to them claiming otherwise. The deathdapter it came with was wrong, it had a US plug on it not an Australian plug, not really a big deal because I’ll probably just replace the whole power supply in any case. The power adapter itself is a little chintzy, feels flimsy on the outside, the internals look OK-ish but I’ve not done a megger test on it yet. The main body of the machine is all plastic.
The design is rock simple, basically you have a torsion spring wound in the top section which the “actuator” is attached to, in the bottom there is a gearmotor which drives a dog which engages with the actuator end of the spring to draw it back, the “power” control, basically adjusts a slot which causes the actuator end of the spring to slip down over the tip of the dog releasing the spring tension and driving the actuator forwards.
It seems that the “new” version (website indicates that the “new version is 30% more powerful”), may be of a different design to the one featured in the SPKM-MAK-3 video on their website (presumably the “original”). From what I can tell from the video it looks like the original actively drove the actuator, because after each stroke it seems to “hunt” for it’s zero (this is visible by the slow motion forward movement after each stroke prior to drawing back for the next), I may be wrong though as I’ve not taken video of the unit I have so I can’t tell for sure that it’s not just an artifact in the video.
The upshots of the rock simple design are; it’s unlikely to have a mechanical failure (unless you break the spring, though there might also be some risk of “wearing out” the power control), and that makes it an awesome candidate for modifications. More on that later.
Given its size it’s pretty punchy, not quite what I was hoping for (I was really looking for something that could deliver on “six of the best” with a cane), but with the right choice of implement and orientation it does the job pretty effectively.
Paddles and such seem work best with the actuator arm operating in a horizontal plane (machine upright or upside down), canes and similar seem to work best with the arm operating vertically, (i.e. such that the cane is coming downwards). To my surprise the most “punchy” implements I tried with it were a ~4mm plastic coated fibreglass garden stake type thing which I think was bought from Daiso, a stock standard 30cm wooden ruler (the hole in the end of the wooden ruler for hanging it adds significant extra effect) and a riding crop. In a nutshell, if you want a severe session, plan to go long rather than hard.
The mounting is not as solid as I’d like, but given the objectives of the device manufacturer that’s not terribly surprising. This will also be something I will be looking at improving (and adding some features around) in the future (pile of parts en route from Banggood currently).
The good
- Decently punchy for its size (even if it’s not quite as punchy as I’d like).
- Amusing packaging, they’ve really gone to town on making it look like something other than what it is, right down to the nameplate on the bottom of the main unit.
- Excellent hackability.
- Simple design should hopefully lend good longevity.
- At first blush the “actuator” appears to be some kind of glass reinforced nylon so will hopefully hold up well.
- The octagonal mounting system is a novel way to get angle adjustment.
The bad
- Mounting hardware is not as claimed, and is a bit sloppy in general which will be causing some loss of energy from the “business end”.
- It’s quite noisy, but with any sort of impact toy some level of noise is unavoidable so I suppose that’s not a big deal.
- Potential wear point on the “power control”. Remains to be seen how much of an issue that will be.
- The timer is a cute idea but IMO not terribly useful (also quite noisy), if it weren’t clockwork so it only operated when the power was on it would be more useful, my first mod will likely be adding a bypass switch.
- The price is a bit iffy, I can understand why it is where it is (because tools for plastic injection molding are REALLY expensive), but for what you get it feels a bit high.
Conclusion
Does the job pretty well, though you need to be a bit careful with your choice of implement. A little on the expensive side. I’d provisionally recommend it so long as you’re not looking for heavy hitting. I may buy a second unit in future so I can use them “in stereo”, though then I’ll have to start buying duplicates of all my implements…

Such a funny machine .
I read that it is a kneading machine ?
Now I am curious , what was this machine supposed to be kneading ? Food ?
Is it written in the manual maybe what kind of machine this originally is ? ?
Good review by the way !
The machine is most definitely NOT intended for kneading. Weeeell, I suppose it’s *kinda* like kneeding…
It was designed and conceived for the purposes of delivering spankings, the branding and so forth is intended purely to obfuscate that purpose in order to avoid issues shipping it into, shall we say “more conservative” markets. The original version of this review did explicitly call it a “Spanking Machine” but at the manufacturer’s request I dropped that out of the review title due to concerns about impacts on shipping into those markets.
Looking for info on KER K-3000, I discovered your excellent review. I can support your good points as well as the bad ones. Yes, it could well use mor than the 30% more power, but if you go over the full 5 minutes of the timer, you will feel it, especially with hard material as a wooden paddle.
I have kept to the 100g rule for weight. But that does not really slow the machine and the impact is still acceptable.
The mounting device for toys is clearly improvable: It could be more rugged (My next walk to the hardware store will be for a bag of replacement screws). However a drastic disadvantage are the flat plates for mounting round toys. I am going to replace the movable plate by something like you use for fixxing all kind of pipes to the wall, i.e. some kind of shell. Otherwise, your cane will start hitting your bottom and the next thing you will feel is a hit into the hollows of your knees.
By the way, I have a switchable on off extension cord right at my hands; just for emegencies like sticks flying through the room.
I have the machine mounted to one wooden post of a 4 posert bed. That opens a lot of options to point the spanker in direction to the bed and also into the room for vertical “work”. The clamp which included is rather restrictive.
All in all: a nice toy and amusing spanking option.
Yeah, 100% agreed on the “mounting device for toys”. I’ve not had a great deal of free time (as evidenced by the lack of updates to this site 🙂 ) but I’m planning to design some 3D printable end-effector clamps to better hold awkward shaped items. They’ll be published on Thingiverse once I get to a design I’m happy with.
So stuck at home thanks to lockdown & no doubt more to come where can I order one
Found this as I started looking for KER-3000. I got one of these machines, and the black mounting part for connecting the rod to the machine body has broken. It broke right where the screw goes through, to hold the rod in. No biggie I thought, design a new more beefy and print it… But after taking it off, I see that nothing is actually symmetric. The 6 small screws are self tapping into the plastic, and they are all at different heights and positions from the body, so it is a real pain in the butt (pun absolutely intended) to measure.
Intriguingly, there is a kitchen machine (by Braun) model number K3000 (full name: Multiquick 7 kitchen machine K 3000).
See:
https://www.braunhousehold.com/nordic/all-products/food-preparation/kitchen-machines/multiquick-7-kitchen-machine-k3000-0x63210703
And it does, of course, come with a kneading attachment.
And did you ever publish your 3D printable end-effector clamps design on Thingiverse?
Nice find 🙂
You might have noticed a lack of updates on this site 😉
The past few years have been pretty crazy busy, but once I actually get my 3D printer reassembled this is one of the projects on my “get back to it” list.
Hi! Did you ever get around to making this?
Not as yet, just moved again :/
Theoretically I’ll have somewhere to permanently setup my 3D printer after I finish remodeling this office so maybe I’ll have time to get back to this some time next year 🙂
This post was one of the first comments. In the meantime, we have the remote control version of Spanker machine. I would be very interested to hear/read about your experience with new models of KER and wheather you have improved on some of the weaker parts.
I have collected some impressions working with this remote control. You have three modes of operation: 1. continuous strikin, 2. random striking 3. selected number of strikes.
All of that is nice to have, however, my first point on the wish list would be another mode of action: selecting the time between hits. With that feature, you could really “get in the mood”.
I wonder wheather anybody of your readers would dissemble the remote control and add that additional feature. I imagine, it should be possible for an expert,
I am the owner of two machines, one has not survived (spring broke); the other one is about to give up because the “half moon” connecting the machine with its mounting arm is too weak to sustain the backslash when releasing the business end. It is a preprogramed breaking piece. I have replaced at least a dozen of them. The point is not getting the replacements from Juan, but the progressing weakening of the screw threads on the machine housing due to the frequent replacement of the half moons. I have contacted Juan and he knows about the problem. The hafl moons will have to be replaced by something mor stout made of metal. Otherwise I am quite satisfied. Especially the good support by Juan Angel.
A tip for self-tappers in plastic, when you are putting them back in turn them backwards until you feel them drop into the thread then tighten them, that way you’re not cutting new threads every time you put them back in.
Hi,
I have never heard that you can get a screww in by turning it backwards!? But its worth a try!
Thanks and best regards

I just received mine. I’m pretty sure I can make a mold of that plastic clamp. I guess it’s time to fire up my hobby foundry and cast one out of aluminum.
That’s an excellent idea.
Unfortunately my foundry is *somewhere* under the pile of stuff in the garage still to be sorted from the move 🙂 but I’d be interested to hear how it goes for you.
Nice to hear from you. Juan Angel has sent 2 NEW Half Moon couplers. They look and feel different, however they are made from plastic again. Juan thinks they will not break, but it would be great to get them made from metal.
Hi! Did you end up making a new mold?
Die Halbmonde sind bei mir auch schon 2 x gebrochen; habe sie mit Gummis sowie einem darüber geknoteten Schnürsenkel aus Leder fixiert; ist nur eine Zeit, bis sich das Ganze locker / verschiebt. Halbmonde aus Edelstahl wären wirklich ein Traum. Leider ist das Gerät auch ziemlich laut. Ansonsten für den Preis aktuell unschlagbar. Habe keine Alternative bisher gefunden.
Since my first purchase, I have killed two machines. One was repaired several times. Then I got a replacement that was defect pretty soon.
Now, I have a fairly new K 3000 Silver as replacement, and that machine is still doing well.
As to the issue concerning halfmoon couplers: The new ones did not break anymore.
My machine broke cause it couldnt handle when i turned the power up to try getting more impact. The motor came flying off the base while still on spanking mode…fortunately i wasnt close to it at the time. The plastic part attaching to the base with the screw, completely split in half. I cannot use it right now.
I have the “improved, more powerful” silver unit. No problems with it so far. This thing will swing a dressage whip as hard as you can stand it! It came in a tough, opaque plastic bag, very discreet.
Good to know, I’m pretty sure the damage to my units was as a result of attempting to use quite flexible canes at high intensity and as a result most of the kinetic energy was going into the stop rather than the implement, so I imagine if the new model can swing a dressage whip that well that it should do well with a cane as well.
I am about to post a detailed warning about this issue. I have destroyed two machines by busting the spring exactly by letting most of the energy bomb into the stop. There is virtually no leather implement except a stiff flatt paddle that will not bend.
i cant find the “c clamp” for the rodt that fits into it is there a part supplier plz help
From what I’ve seen in other comments here it seems that the creator is pretty accommodating, ping them an email and they’ll probably be able to help.
