I made a complete library for adding screws, nuts, and washers to any project. I’ve been working on this the past few days.
It’s pretty simple to use. Set your tolerances in the file, then call the functions or modules.
for example: screw_hole(screw_M3) will create a screw to be used for subtraction to create a hole.
screw(screw_M3) will create an actual screw. (not for printing, representative only)

screw_hole_allowance = 0.15;

rod_hole_allowance = 0.15;

nut_hole_allowance = 0.15;
nut_thickness_allowance = 0.15;

washer_hole_allowance = 0.5;
washer_hole_allowance_tight = 0.15;
washer_thickness_allowance = 0.01;
