Nerf Longshot Bolt

thingiverse

These knobs always seem to get lost. 3D printer to the rescue! To assemble, I bought a piece of steel rod from the hardware store. Before attaching the knob, I sanded down the rod slightly, so that it was smooth. Next, I used a hairdryer to heat up the knob, then press the rot into it. Super glue can also be used for a more secure connection. because the length of the rod varies between longshot, vulcan, and centurion. I ended up sticking the rod through, and eyeballing it. So far, it's working well. Print Settings Printer: D-bot Rafts: Doesn't Matter Supports: Doesn't Matter Resolution: 0.2mm Infill: 50% Notes: I printed mine with a 0.8mm nozzle. The important part is that the layers bond together.. if your printer has sub-par layer adhesion, the knob could fracture along the z axis while in use.
