Summary

A useful little assembly aid when you have fiddly parts you want to join together. Just put some 1/16" holes through mating parts, run a 1/16" drill through after printing and verrrrry carefully push in these pins to hold the bits together, with or without glue.

Make sure you specify a raft to prevent coming back to a tangled mess of plastic. Snap off at neck to give you a handy little 1/2" long x 1/16" dia pin.
