Exact same file as the one posted by HarderDIY just with the model rotated so it prints on end. Find it easier to remove the supports that way.

I printed at 0.75 scale for a more reasonable size for a keychain.

I may re-upload this with the prongs on the male end separated a touch as it has a bit more play than I would like when buckled together.

EDIT: This is maybe not the best idea at 0.75 scale with PLA... broke in less than 24 hours due to the layer direction I think...might be better with PTEG or better layer adhesion. My printer isn't tuned the best right now so might be a me problem ahaha
