3D printing1 partNo supports
An M6 screw with a knurled head and 20 mm of ISO thread, for small clamps and adjustments you make by hand. It holds a lamp or camera arm in place, locks a lid or sliding stop, or replaces a lost knob on a printer enclosure, a music stand or a bike rack. Print it standing with a fine layer height as in the print settings, test the thread with a metal M6 nut first and tighten it by hand only.

Worked for others:
Tip: Print as shown: bolt standing on its head, nut lying flat, no supports needed. A layer height of 0.12–0.16 mm makes the thread cleaner. Printed bolts break more easily than metal ones – don't tighten them hard.
Estimated by our slicer-like calculation for a 0.4 mm nozzle. Your slicer may show slightly different values.
