This is a parametric case for the WaveShare 4.01"E e-ink Spectra panel.
Do not use any supports as they will clog the kickstand. Printed with default settings (0.2mm layer, 0.4mm nozzle).
The STL fits a raspberry pi zero with angled pin connectors and a modified HAT (remove the 40pin connector, use the 8pin).
You will need M2*4*3.5 heat set inserts for the cover, and M2 screws to screw it in from the back.
