Due to requests, I have added a centre piece, hopefully this should complete the set.

This repair part was originally done for a friend. I've updated to include a 3 pole part, its a quickly rehashed part, but should work ok I've included a 3 pole version with reinforcing fillets on all sides. There is a version of this part that is completely hollow at the intersection, this is the V2 version, it saves filament and prints approximately 1hr quicker according to cura compared to the original. I'll leave the original on as it is probably a stronger part.

These are made for a pole diameter of 20mm, the hole is 20.8mm.

I made this from PLA with 100% infill.

I'm making no guarantees regarding durability.
