A DIY 3D Printed Rocket Launcher
After successfully launching a multitude of my 3D printed Bounty Towel rockets, my kids and I decided we needed a more badass rocket launcher than the bland and generic store bought mass manufactured versions. My biggest complaint with the generic store bought models is when you press the switch you get very little feedback on what is happening. This is especially concerning when the rocket doesn’t immediately launch. There is also ample opportunity for improvement in the aesthetics department on these devices.
If we wanted an awesome rocket launcher we were going to have to print, build, wire, and assemble it ourselves!

DIY MODEL ROCKET LAUNCHER CONTROLLER WIRING DIAGRAM


These are utterly amazing! Are you planning to sell them, or release the .stl files and detailed part list? I know a lot of my friends would love them.
Any chance you’d publish a wiring diagram?
Updated to include wiring diagram.
I would like to build one of these to use when my son and grandson are visiting. My son and I launched rockets when he was young, and I’m continuing the tradition.
Might you be willing to share the STL for the case? I can print it on my own Prusa 3D printer.
Thanks!
Website updated with download link for the enclosure.
Thanks for uploading the 3mf file. I paid for it and downloaded it. It comes in as one object, and I don’t think it will print that way. Can you give me any advice?
