Hello,

I am having a model including screw-like mechanism in vertical direction and I am intending to print the structure on one print, so the male part is already printed inside the female part.

What could be a sufficient spacing to be used between the "screw" and the "hole" so the parts wouldn't melt to each other?

This one goes for school project and I'm having only one print so I'm trying to succeed at once.

Printer used for printing will propably be Ultimaker S5 Pro Bundle FDM- printer.
Available nozzle diameters: 0.25 mm, 0.4 mm, 0.6 mm, 0.8 mm
Filament diameter 2.85 mm
Material used is unknown (PLA, ABS, Nylon, PVA, PETG, PP, PC, CPE...)
Layer thickness 0.02-0.6 mm (depending on the nozzle used)

Based to my minor knowledge, I assume that by using 0.25 mm nozzle I should have at least 0.25 mm spacing between the parts(?)
