Core One Low & Narrow Squash Feet

After converting an MK4S to CoreOne+ , I needed better damping for a narrow shelf setup. Existing mods were either too tall or too wide, so I designed these feet to stay low while still using 8 squash balls for effective isolation.

There are many fantastic mods already available, for example:

• really tall, narrow, not antivibration 1217232-prusa-core-one-feet-v2

• medium tall, narrow, with 4 squash balls 1227024-prusa-core-one-feet-v2-squashball-version-anti-vib

• medium tall, narrow, with 4 squash balls 1212421-prusa-core-one-squash-ball-feet

• low profile, wide, with 8 squash balls  1228654-prusa-core-one-squash-ball-feet-low-profile-v2

However, none of these fit my purpose—they are either too tall or too wide.
My requirement was to keep the printer low while also maintaining a narrow footprint, as it sits on the top of a narrow shelf.

Design Overview

• Uses 8 squash balls

  • Suggesting double yellow dot hardness

  • 4 are squeezed inside the printer’s hollow base

• Designed to keep the printer low and narrow

• Feet are modeled around the stepper splitter, which can remain stock 

• Updated to version 2: Feet can be attached in either position - visible squash balls front/back or left/right

Mounting

• Supports up to 3 mounting holes aligned with base frame holes

  • update to version 2: with an additional screw hole

• 1× M3×10 screw in the center is sufficient, this hole in the base has m3 thread already, use either of the center holes depending on chosen orientation

• I used leftover screws from the disassembled MK4S

Printing Notes

• Print 2 left and 2 right feet

• No supports required

• Tested material: PLA-CF

After one week and several completed jobs, everything looks good, but most importantly SOUNDS great.
Hope someone finds them useful 👍
