SUMMARY OF CHANGES MADE WITH THE VERSION 3 !!!
The current version of these is 3. They use over 55% less plastic than the previous edition and are over 2.5mm lower as well. I also decreased the thickness of the walls to increase the flex and this results in better dampening ( TESTED with phone app shows 5 to 10 dB decrease over original when in LACK enclosure ). The modified idea of the foot that goes by the electronics case comes from j3zm0n7e and lowering the Z-axis foot 3mm was thought of by Pencilneck ( Check out their remix of the v2 for the lower z-axis foot ). I also want to say thank you to anyone who downloaded the past versions as well !!!
What If I Have A Mini Base ? Will They Still Work ?
I have not tested anything yet with the Mini Base but if you use 4 of the Z Axis Feet then they should slot into the legs of the Mini Base. I may also design some dampeners specifically for the Mini Base but this is still not for certain.
Why I Made These
After looking around a common solution for dampening feet for the Mini is to use squash balls. I don't doubt this wouldn't be effective but I believe that this is a little over the top and complicated as there are different sizes of squash balls further complicating the process. And being a student with little excess cash, saving money where possible is always a benefit :) . So I decided to design a simple, single 3D printed piece, solution. This design is heavily inspired by similar feet for the ender 3 designed by redmaxver.
Please consider leaving a like as it means a lot to me, 2 seconds of your time for many hours of mine seems like a good deal.
Additional Comments:
- You need to remove the foam foot underneath the z-axis and then you can insert the printed foot in its place!
- For quantities of each foot to print read the file description!
- Printing these in either PLA or PETG will work fine but with PETG being less rigid than PLA it may result in better vibration reduction. That said the new version 3 has thinner walls and using PLA will be more than sufficient!
- The dimensions of the included .stl files are optimized for printing at 0.2 mm layer height. They also print support-free :)
- I also strongly recommend printing these with a brim or raft as there is a little surface area on the first layer. The pre-sliced gcodes all have brims!
Happy Printing :)
Update Log:
Date 01/02/22
- Small update: I’ve added a modified Z axis foot designed by Sandysasmita. This foot doesn’t require removing the foam foot under the Z axis and I recommend using this foot instead of the original one :)
Date 10/09/21
- I have uploaded 0.2mm/0.4mm/0.6mm Z Axis Feet under the experimental files folder :)
Date 12/07/21
- I have uploaded some more experimental feet, one that's 1mm tighter around the foam and another that's 2mm tighter. 1mm = 0.5mm on all sides. If you need a tighter version then ping me in the comments and I'll upload more right away.
Date 9/07/21
- I am no longer pushing development on this project, I feel it is now at a point where any improvements I make will be so subtle it will have little to no effect on the final results of reducing the printers noise. I have also installed the Prusa Mini Base on my Mini so my feet have become obsolete. If you still want to use these feet with the base, using 4x of the feet for the Z Axis should work fine. I may also work on a new design to integrate cleanly into the new Prusa Mini Base but this is not set in stone yet.
Date 15/06/21
- I have uploaded a new Z-Axis foot with tighter clearances, sorry for the later than expected release ( added a 0.8mm offset so will be 1.6mm wider and longer ) I have not tested this new foot out yet so it is not yet included in the pre-sliced gcode. If you've printed it and it works or have any suggestions then hit me up in the comments :)
Date 22/05/21
- I have tested using PETG and find the results to be much superior to using PLA. A tighter clearance foot that goes under the z-axis is also in the works. Releasing sooner than later. Also trialing an ultra-low version, but this would only work with PLA due to the flex of PETG.
Date 25/04/21
- Version 3 release: These feet are not compatible with version 2 or 1 due to size differences and other things, so if you need the old versions then click the link at the top of the page!
Date 14/04/21
Date 10/04/21
- Uploaded the Z-Axis Edition, this replaces the foam foot that supports the Z-axis, also updated description accordingly and print files, etc.
Date: 18/02/21
- Updates made in regard to changes made to PrusaPrinters and the ability to add folders etc…
Date: 07/02/21
- I made some updates to the description and updated the print files, added a new version of the PLA and a PETG file ( this can be found in the user print files section ) - 18/02/21 - These files have been relocated to the "Print Files" section.
Date: 04/01/21
- I have uploaded new feet ( 3mm, 4mm, 6mm, 7mm ) with different depths. I haven't experimented with them to find an ideal combination but what works for one printer may not work for another as it depends on how much the foam feet have deformed.
Date: 24/12/20
- You may need to add little pieces of paper into some of the feet to act as a sort of spacer. I found that when placed my printer on an Ikea Lack table it rocks slightly. After a minute this was eliminated with some simple little pieces of paper place inside/underneath some of the feet.
