I think you are maybe looking for children() <https://en.wikibooks.org/wiki/OpenSCAD_User_Manual/Modules> module hole(distance_x, distance_y, rot, size) { difference() { children(); // - rotate(a = rot, v = [1, 0, 0]) { translate([distance_x, distance_y, 0]) { cylinder(r = size, h = 100, center = true); } } }// hole Then you can do hole(32,15.5,0,5) hole(32,75-15.5,0,5) box(40 + 12 + 12, total_width, 12); etc. ----- Unless specifically shown otherwise above, my contribution is in the Public Domain; To the extent possible under law, I have waived all copyright and related or neighbouring rights to this work.
