1/2" EMT Conduit Connectors

I began designing these to make a custom cover for my generator. I'll be sewing the cover soon to fit over the frame.

I made several other types since they are all just different configurations of the same design. These could be used to make all kinds of structures out of cheap 1/2" EMT conduit.

The hole for the conduit is basically friction fit, but not super tight. I added hole that can be used to thread 4mm screws for a tighter fit. This is what I did. If you go that route, be careful not to overtighten the screw. Another option would be to drill holes in the conduit and screw through the fittings into the conduit for a much more secure fit.

The conduit hole on the the "through tee" is slightly larger to accommodate sliding over the conduit. I included a smaller cap and through hole piece that can be used to test your printer settings and tolerance.

I don't know that I would use this for anything very structural, but worked nicely for my purposes. I'd love to hear suggestions for other uses or how they could be improved.

I printed mine using PETG, 0.28mm layers, 4 walls, and 15% cubic infill. No supports should be needed.

EDIT: I had a request for a 5 way connector. I added 1 solid and 1 with a through hole.
