Mini-DIN Top Hat Rail Clip

A clip for a modular Mini-DIN top hat rail system. Overall clip width is 8mm.

Location divots are provided for a mating part. They are female on the clip, so a simple slot will work on the mating part too.

The hole counter-bore is suitable for a #4 (2.9mm) self tapper or an M3 pan head screw. I find cyanoacrylate glue provides an extremely strong bond too, so you can do without screws if you want. Generally, if you glue this with CA glue and try to pull it apart, the plastic fails first.

Side holes are suitable for inserting filament as a pinning system. They are also co-incident with Weidmuller AKZ15 Mini-DIN terminal blocks.

CadQuery source is provided so you can adjust the clip as needed. Depending on the printer, you may need to adjust the grip location to give a firm snap action. This is result of much trial and error to get a good action, but will depend on your printer and materials used.
