Hinged Phone Holder

This hinged phone stand is foldable so that you can take it with you anywhere. The hinge part requires a 82mm(ish) piece of 1.75 filament inserted through the bottom to rotate on. My intent was to melt the end of the filament to fuse it to the bottom of the hinge so that it wouldn't fall out, however, I have used mine for a couple of weeks without melting it and the filament hasn't fallen out.
