Balcony doorstop

Doorstop for mounting on 1 1/2" balcony rail pipe.

Printed in PLA: the application may need ABS, but that remains to be seen.

Added an update to the clamp part, where the clamp has some room in it's material for temperature shrinking.

This PLA doorstop seems to hold out well, by the way: it's been sitting out there for a few years now.
