Black Powder Motor (Estes) Stand-ins

thingiverse

I designed these BP motor stand-ins to serve as reliable alternatives, allowing me to easily add weight and match the specifications of a full motor for simulation purposes. This way, you can avoid handling live motors or contaminated used ones altogether. Using my 3D printer has given me the freedom to experiment with innovative solutions, like this one. I opted for a friction cap instead of trying to work with the 13mm motors, which proved challenging to thread correctly. I've also added a 29mm motor case to expand the capabilities of these stand-ins.
