4"-4 Nut and Bolt

A large nut and bolt. 4"-4UNC. Center of the bolt is hollowed out to save material.

This was designed in imperial units so if your slicing software shows it tiny then scale it up 2540%. The shorter bolt height should be 8.6875" (220.6625mm), the longer bolt should be 10.000" (254mm). The nut height should be 3.000" (76.2mm).

Fell free to post a make.
