Edit 2021-09-15: Updated the FreeCAD file to V1. Looks nicer, has less different features and still can be customized as you wish.

Edit: I added a fully customizable (FreeCAD) version. Feel free to download, modify and re-distribute to your hearts content!

You can change all the parameters you want. For example (in "Sketch" of the MainBody):

  1. height of the knob
  2. maximum depth of the encoder shaft into the knob
  3. diameter (radius) of the knob

Or the shaft bore:

 

Thanks to Lucien for the nice buttoon/knob.
I am using a nearly identical one for quite some time now (of which I don't have the files anymore, doh!).

The original that comes with the printer should've been ditched by the Prusa team long ago, it's a pain to use…

Anyway, I made it 6.5mm higher, so now it is 15mm high. It is easier to use with thumb/index finger scroll action this way.

No .STP file this time, as this is just a very quick “hack” of a already nice .STL.
