Silicone damping feet with adjustable height. Geeetech A10, Creality Ender 3 etc.

These feet fit on 3D printer with 40 mm aluminum extrusions like Creality Ender 3 or Geeetech A10.
For the silicone parts I used 2-component silicone from "Troll Factory" (Germany) which I also used for some silicone socks and heatbed dampers for my Geeetech A10.

There are some tutorials on how to use 2-component silicone on YT. Like on the CNC-Kitchen channel.

Previously I used these feet: Thingiverse 3515471, which are good, but to me they seem to be a bit too soft, that's why my printer started to shake easily while printing. Because my A10 is heavier in the left side it also stood crooked on these feet.

Update 15.10.2020:
Added TPU-Damper.STL for people who rather like to print TPU dampers than to print the mold for silicone dampers. I haven't tested TPU for the dampers yet. I guess you will need really soft TPU for this.
