Clipfeet Mini

A clip/shim designed to fit onto the Prusa Mini's frame profile. The printer's frame has 5 support feet in total: 4 standard feet and a 5th, black foot located under the mainboard enclosure, along the Y axis.

This clip includes an oval plate that is meant to be used only under the 5th foot, under the mainboard enclosure — it's not intended for the other 4 standard feet. It acts as a roughly 1 mm shim there, meant to raise that foot slightly so it can sit closer to level with the other 4. On my own printer, this seemed to help with weight distribution across the support points and appeared to reduce vibration and improve stability — but results may vary depending on your specific unit, so use your own judgement and check the fit before relying on it.

It may also be worth trying if your original feet are worn: the shim could help compensate for lost height. Again, this is based on my own experience and not a guaranteed fix.

The project also includes a mold you can use to try casting your own silicone feet, as an alternative to the stock ones — this is optional and provided as-is for anyone who wants to experiment with it.

Included in the kit:

• Clip/shim with oval plate, designed to be inserted under the 5th (black, Y-axis) foot

• Mold for casting silicone feet (optional, experimental)

Recommended Print Settings

These are the settings I used; feel free to adjust based on your own printer and experience:

• Material: PETG (chosen for mechanical resistance, as it's a structural part in contact with the frame)

• Layer height: 0.15 mm for the clip

• Infill: 30% for the clip, 15% for the mold

• Perimeters: at least 3

• Supports: check based on part orientation in your slicer

• Orientation: printing with the frame-attachment surface flat on the bed may help with fit accuracy

Assembly Notes

This is how I installed it on my own printer — check fit and stability carefully before trusting it on yours:

1. Locate the 5th, black foot, positioned under the mainboard enclosure along the Y axis.

2. Remove/loosen that foot from the frame.

3. Clip the printed shim onto the aluminum profile, with the oval plate positioned under that foot only (do not use the oval plate under the other 4 feet). The oval plate has a smooth side and a grooved side: I used double-sided tape on the smooth side to stick it to the base under the enclosure, and put the original foot's glue on the grooved side — you may want to test your own approach.

4. Reinstall the foot on top of the clip — it should now sit slightly higher than before.

5. Check that all 5 support points sit flat and stable on the ground before printing.

Disclaimer

This is a personal project shared as-is, based on what worked for me on my own Prusa Mini. It's not an official Prusa part, and I can't guarantee it will work the same way on every unit or setup. Print and install at your own discretion, and always double-check stability and fit before normal use.
