I’m having trouble pushing from two different directions when they cross each other. The attached skp file is a knob for the Z shaft on my 3D printer. The slot in the top is for a nut and the hole in the front is for the screw. How can I make the screw hole go all the way through to the shaft and have the slot push down 13mm and keep it free of residual “tunnels” or blocked holes?
