These simple, click in mounts for inline WAGO 221 connectors can be fastened to a surface using M3 hardware (I used socket cap screws, which should sit below the surface).

I have included a single, double, and “filler” piece that can be aligned and merged directly in your slicer to create a single mount for any number of connectors you could need.

These are based off of the clever (and awesomely simple) design from Jack Ormston. They hold the connectors firmly, but still allow you to pull the connector off if needed.

These should be printed on their sides for strength, no supports should be needed - the overhangs are small enough to not really matter.

.STEP files are included for additional updates and modifications as needed.
