Screw Coat Hook

I wanted a fun giant screw to hang bike helmets on in my workshop. I modelled up an M5 hex socket button head screw in Fusion360, and then worked out a way to have the wall fixings hidden by allowing the thread part and the screw head to unscrew. Once the thread part is screwed into the wall using two counter sunk head screws, the head can screw on. I then exported as step files and scaled up by 1000% so that the thread part was now 50mm diameter. At this scale it printed pretty well using standard settings in BambuStudio… the thread is a bit rough in places, but not too bad.
