The knob on my 3D SpaceMouse became sticky over time, so I designed a replacement part.

The replacement consists of two parts: the main knob body and a twist-lock cover that hides the mounting screws for a clean look.
I wanted to make it look a bit nicer, so I went with a two-color design with a pattern on both the knob and the cover.
Print Settings
Layer height
0.15 mm (both knob and cover)
Material
PLA Prusa Galaxy Black (main)
PLA+ Eryone Azure Blue (pattern)
Knob (main body)
- Printed top-down
- Supports: yes (concentric interface for easier removal, 0.2 mm contact Z distance)
- I used seam painting in PrusaSlicer to align the seam with one of the three mounting holes — this way you can place the knob so that the seam will be hidden at the back when mounted.
Cover
- Printed top-down
- No supports needed
To mount the cover, align the three pins with the cutouts and place the cover on the knob.
Slightly rotate clockwise to lock it.
To remove, rotate counterclockwise and lift off.
