Photo Equipment Screws

one is 3mm unthreaded then 6mm threaded
the other is 25mm threaded
I made a test-print with a crazy outer layer height of 25 micron -yes- 0.025mm. The print worked but there was some waving reducing resolution and making the surface rough. Nevertheless it turned out very usable and especially sturdy against breakage through sideward bending.
Use the ancestor thing to generate alternate versions.
The commands to generate this two screws where:
hex_screw(25.41/4,25.4/20,30, 25,0.5,2,25.47/16-0.15,4,3, -1);
hex_screw(25.41/4,25.4/20,30, 6,0.5,2,25.47/16-0.15,4,0, 0);
