thingiverse
Overengineered parametric jig for drilling through aluminum extrusion. A metallic nut is used to reinforce the jig. First time drill-through to remove thread. Default settings are 3030 extrusion, an 11mm hole, M10 nut, and a 12-25mm distance from the edge. All values can be modified in Onshape, please refer to the screenshot.
