Knurling bolt and nut
cults3d
There are knurling bolts and a nut that modeling on Autodesk Fusion 360. I've prepared a bolt of various lengths. So, print a bolt you want. Bolts are M16, pitch 2.0, length 20, 30, 40, 50, 60mm, and Head OD 30mm, height 20mm. A nut is M16, pitch 2.0, height 20mm. See my YouTube about how to making a knurling on Fusion 360 https://youtu.be/wNVtLVF99cw "Knurling bolt and nut" are compatible with "Yet another knurling bolt and nut" (https://cults3d.com/en/3d-model/tool/yet-another-knurling-bolt-and-nut).
