Bolt safe

thingiverse

I decided to give this bolt a more authentic look, so I grabbed a bolt and a nut from Fusion 360's McMasters-Carr parts library and made some adjustments. To get started, I printed the nut and the head of the bolt without any brim support. However, since the bolt is quite long, it's better to print it with a brim to ensure stability. Update: I added a new version of the bolt featuring a smaller inner hole that should provide increased strength when scaled up.
