Updates

  • June 6, 2021:
    • Improved the slicing options to result in softer feet
    • Added a much larger version of the feet for increased dampening

Description

I designed these feet as a 1:1 replacement for the original feet on the Tefi KC-1 Ra. Depending on the material they are printed in, they can hardly be distinguished from original ones:

I recommend printing them using ColorFabbs varioshore TPU filament at 220°C. But you can use other flexible filament as well, most likely resulting in harder feet. The provided 3MF and G-Code files are optimized for the varioshore filament. SO you might want to adjust the settings when using other material.

There are two sizes to choose from:

  • The original size (as it came with the Tefifon): 13 mm x 7 mm
  • A much larger size (for increased dampening): 21 mm x 16 mm

The feet mount to the device using the original screws (M3 + tiny washer):

Design and Source Code

The feet have been designed using OpenSCAD. I have provided the source code for download, so you can adjust the design to your needs.

Happy printing!
