PLA Filament

We recommend printing the parts in PLA filament. Follow our slice settings as a reference point. Settings will vary from printer to printer, so you'll need to adjust your printers settings accordingly. Each part is optimized to print with no support material and saved in the best oriention to print.

Prop Details

We recommend printing the dhp-grip-bottom.stl and dhp-grip-top.stl parts together in a set. The dhp-dot.stl pieces can also be printed in one set to speed up the process. Most slicing software can allow you dubplicate STLs. This project uses 12 dots, 6 on each side.

Finish Part Surface

We added a light coat of silver spray paint to the parts to give it a metal look. Using sand paper and a brass sponage, we smoothed out the surface and added abasion to the parts giving it a worn and aged textured.
