Build instructions for the project are here: https://gerotakke.de/ottopotThere's a top case for the version with LEDs and one for the one without.  For the knobs, I'm using this model: Encoder Knob by Void, the 16mm_3mm_D.stl file printed at 103% scale on my Prusa Mini. I suggest printing 1 and checking the fit before committing to print all 8 in one go.  In my models I'm using 0.2mm tolerances for all the holes but I think my printer isn't tuned perfectly so I also need to clean up the holes after printing with a drill a tiny bit; for the pot holes I use a 7mm drill, for the small LED holes I use a 2.5mm drill.  I use 4 heat set insert from CNC kitchen in the bottom case and 4 generic m3x8 screws with allen heads to fasten the top case to the bottom.  Finally I use a couple of 3m rubber feet to glue onto the base to prevent slipping. I have used PLA for all my cases.
