Printer all set up and calibratedTurned your wonderful code into a stl codeNow to figure out once I put it onto a SD card how to get 3d printer to printJust a little confused on one thing, the whole in the axle, if the axle object will slide onto is 1.9mm so should I change your value to 1.95mm or leave same?Really getting there, even installed cure ( 2018 Version) which came with unit, asked if I wanted to update, should I have?TYJeff$fn = 90; // smoother surface of cylindersaxle_diameter = 2;disk_thick = 1;disk_diameter = 10;short_stem_height = 2;long_stem_height = 5;stem_diameter = 2;addabit = 0.0625; // provide overlap to avoid z-fightingmodule assembly(){ cylinder(h = disk_thick, d = disk_diameter); // main disk translate([0, 0, -short_stem_height + addabit]) // move short stem below disk cylinder(h = short_stem_height + addabit, d = stem_diameter); // short stem translate([0, 0, disk_thick - addabit]) // move long stem above disk cylinder(h = long_stem_height + addabit, d = stem_diameter);}assembly();
