Kossel Tennis Ball Feet

I designed these feet for my Kossel to serve two purposes. First, as an anti vibration measure to reduce noise. Second, to raise the printer up enough to mount a 25A power supply brick underneath. Utilizing the tennis balls as a source of shock absorption is not only a cheap solution it also saves on amount of plastic printed. The felt of the tennis ball also provides a nice surface to set your printer on the table without scratching it. The tennis balls fits snugly inside the feet and although they can still be removed if required, they stay in place when picking the printer up. The before and after sound level is astonishing. I cannot overstate how much less noise my printer makes now. I would have never believed it until I heard it.

Mounting hardware required:

  • (6) M4-.7 x 10mm machine screws
  • (6) M4 hammer nuts

Anycubic Kossel Plus










I printed these with 3 top and bottom layers and 3 shells.

I printed the remixed version, helped a ton with noise. Highly recommended.

"2 thumbs up" Thank you so much for sharing they are awesome!

Thank you! I was using some hard packing foam and one corner had started to sag. I hadn’t associated this with some first layer leveling issues that had slowly started happening. After putting on the feet it’s printing perfect and it clicked as to why. So thank you for that and just the fact that these just look good!

Thank you very much! The noise decreased significantly. At what quality of the press has improved, since. there is no vibration.

I have the Problem that the kossel is now a bit silent but it is swinging a lot. What can i do against this? Should i fill the tennis balls with something? I think the kossel is to light weight now.

I'm having same issue, it swings way to easily,

Is this for the kossel mini or not?

It should work for any delta that uses 2020 aluminum extrusions because they all have 60 degree angles between the towers.

Hi, Can this fit a atex power supply under it?

Yes! Here is the power supply mount I made: https://www.thingiverse.com/thing:2504319 (power supply model: 12V 20A S-250-12).

Depends on the size. Not a full size one though. I use it with a 214mm(L) x 112mm(W) x 48mm(H) 12V 25A PSU

Just what I was looking for! Not sure if the Tennis balls I have a smaller or for some reason the cups printed of bigger than they should of but the balls dont fit snug in fact are very loose.

As I said, tennis balls have a size range of 6.54–6.86 cm. I designed these to work with the largest size. If yours are on the smaller end of the spectrum, I'd add a square of double sided tape to the inside. Just now thinking... one of those adhesive velcro squares would be perfect! Just use the hook side of the velcro.

What an huge difference in reduction of noise.
Luckily, I had tennis balls in the closet. :)

Please do email me your mount with fused power socket / switch.

Thanks for the fantastic design.


Here is the power socket bracket I made.

Kossel Fused Power Socket

This is truly amazing! I was expecting a small reduction in noise but WHAT a huge difference!!! Now to solve the vibrations in the arms. Your design is flawless - thank you.

Thank you for the kind words. I thought the same after installing them, its insane how much they cut down on the noise.

Sweet, this is just what I was looking for! Thanks!!

Glad you can use it

Love this.. now I will have to source black tennis balls LOL..
Any luck finding a framework for the bottom to mount the power supply to?

Thank you. I designed and printed a frame for the psu but never published it here. Reason being that the fit was not 100% but I used it anyway instead of tweaking and reprinting it. Also because power supplies vary in size and bolt spacing. I also made a heavy duty bracket to hold a fused power socket / switch. If you're interested in the files I have, PM me your email and I'll send them to you.

You really did all I need !
I have a anycubic kossel plus too, so I think I will make all your designs.
Thank you very much !

You're welcome!
