Description
Bolt and nut test print.The diameter of bolt before thread is 14mm, nut internal diameter 12.4, 12.5, 12.6 mm.
Thread per inch - 12.09/inch
Thread pitch - 2.1mm
Printed at 0.2mm layer has sufficient resolution to produce a workable bolt and nut set. The idle nut diameter for my case is 12.5mm. 12.4 being tight and 12.6 slightly loose.
The diameter of both bolt and nut can be scaled by holding the TPI and thread pitch constant, and maintaining a 1.5mm difference between the bolt and nut diameter.
