note to self... do not attempt to make small fasteners out of PLA... this was an attempted push-fit hinge pin but it just broke as I was attempting to put it together. Enough interference to ensure a snug fit means you have to apply enough pressure to make the fit to break it.

smaller pin diameter on the stepped shaft is 4.5mm... I don't think this will work for anything smaller than say 20mm

Idea was to do something like this... the two parts are 5mm thick and the hole is 5mm diameter, so this was a 15x10 pin

This is just a model and in the real build I'll obviously be using a metal shaft or something, but I was trying to do a quick and dirty test assembly and didn't have a suitable metal pin thing handy
