Summary

Spacers for electronics boards, and so on...

The spacer STL file are setup for 3mm screw.

But in SCAD file you can chage that by changing value variable in header

entretoise_V3 is fully parametric and you can build any spacers as you want

value by default
height=6; //high of spacer + 1 if 6mm you need 7 here
diameter_ext=3.4; // diameter external is wide of spacers
diameter_inter=1.9; // diameter of hole of spacers for screw always add 0.4mm
//example for 3mm diameter 1.5 + 0.4mm = 1.9mm
file_length // distance between spacers
file // size of wire between spacer

iteration // is set 0 one spacers is set 1 2 spacers and so on...

On version 4 you can choose forms of spacers square, penthagon, hexagone
