SummaryMy electric snowblower lost one of the adjustment knobs for the exit chute. So I designed a replacement. I used the pause feature of my Davinci 3D printer to insert a metal nut into the design. I designed a hole just slightly larger than the nut inside the print and then paused the printer when it got to that point and inserted the nut. Then hit resume and the printed sealed the nut inside.InstructionsI used the pause feature of my Davinci 3D printer to insert a metal nut into the design.
