I used Walter's SCAD model to build this case for my digital tachometer.
Remodelled the lid with text. Inner structure added for reflecting tape. Added an opening underneath (bottom) for easier take out.
Printed case on Prusa MK3S+ and MMU2s in PLA. You will need 8 Neodyms of Ø6x3mm. Glued in with UHU glue. Mind the polarity. Here a help: https://www.printables.com/model/671057-north-and-southpole-of-a-magnet
