These are STLs and an OpenSCAD design file for 3D-printable port covers for the Pocket 386 computer. I did not like how easy it was to touch the bare pins on the connectors while handling the computer as this could cause direct ESD to the system bus, so I quickly designed these.
My prints of these fit nice and snug, while still being easy to pop off using a fingernail. I printed them on a clapped-out Ender 3. YMMV and you may need to tweak the sizes a bit depending on your printer. The $connectorw and $connectorh variables in the OpenSCAD file would be the values to tweak, you could try going up or down by 0.1mm.
