Z-shaft standoff

This is an "add-on" for andreasL's alternate Z-axis for the SmartRap Core. I like my bed to be well supported when at it's lowest position for cleaning so I designed these simple stand-offs that clip on to the 8mm shafts in my printer. They support the bed on both sides quite well. The OpenJSCAD code is straight-forward: function main(){ return difference( union( cylinder({r: 10, h: 5}), cylinder({r: 6, h: 45}) ), cylinder({r: 4.5, h: 45}), translate([0,-4,0],cube({size: [20,8,45]})) ); } This hosted file keeps creator credit and license details.
