The hinge pins broke on my kids' Polly Pocket playset, so I designed and printed more.

There are 3 options when printing:

1. Print Vertically - has some strength issues. i.e pulling the pin out will almost certainly cause it to break.
2. Horizontally with supports - requires some post-print clean up.
3. Horizontally, but lower the print into the bed 0.4mm -- strong and no supports needed, but a little looser fit than otherwise.
