anti-vibration feet for PRUSA printers (with K-Flex rubber pad)

Is your 3D printer turning your desk into a giant speaker box?
Vibrations from the printer often transfer to furniture – especially chipboard desks – amplifying noise dramatically.

This simple set of anti-vibration feet fits under standard PRUSA printer feet (MK3, MK4, MINI, etc.).

Just place your printer on these feet and apply a 9 mm K-Flex rubber insulation pad underneath. This is the same closed-cell rubber used to thermally insulate cooling pipes.

📉 In my case, on a chipboard desk, I measured:
➡ ~20 dBA noise reduction

📦 Features:

Drop-in design – no modifications to printer
Fits all 4 corners
Compact and stable

🔧 Print settings:
