Last semester in Entrepreneurship class my partner and I were assigned to make our own company and build a prototype to launch with it. After much discussion we went with the Paint RPG.
The paint RPG is simply a Paintball weapon that utilizes rocket engine tech. to propell a 3D printed rocket with a 12 G co2 canister that releases pressure upon detonation that launches paint in an explosion like manner. Its the first weapon of its kind in the world of paintball and reception from players and courses has been nothing but excitement.
My partner and I were both dealt a shit hand and the rapid prototyping engineers both dropped their class early in the semester. We managed to recruit a military vet. to design our first prototype rocket but after initial trials there were some flaws with the design that need some correction. The flaws are as followed.
Actuator - Works
rocket head - Needs to be threaded to screw into rocket base
Rocket- Needs more internal room for Co2 cartridge and paint pod
paint pod - needs improvement or deletion to work w/o it
rocket fins- Need a small .1 cm reduction to fit snug in launcher barrel
rocket rear - Engine compartment needs to be about .1 cm larger to house C-style rocket engine
For your help with the final rocket design, we would like to give you a % of the company. Our goal is to license the idea to an existing paintball company and move on. I figured the forum would be a great place to ask for help.
Please PM me and ill send you the .STL file to work on.
Here is a power point we used to present to a panel of investors for some insight.
