Hi Jacob,
This is Bogdan from Romania.
I'm a mechanical engineer - specialized in the industrial robotic field, 3D designer and modeler (from time to time and some projects I could make the functional prototype too).
I'm doing product design, industrial design, reverse engineering, ideation, etc.
I have over 15 years experience working on various systems/devices across multiple industries, from concept to launch.
1 - seen the web shooter (blue one) on your youtube channel - cool :)
2 - as you know for sure, there are already 3d models on shapeways and cgtrader (but they really sucks :( )
3 - the web shooter you desire has 3 strings nozzle, but will never be able to create the mesh - sorry (really can't beat the scfi concepts...)
4 - it is possible to make the 3d model (parts and assembly) at almost 95% accuracy of the one in the game, and provide workable files which after 3d printing to fit flawlwsly
5 - as for the active gear, it should have some parameters (maximum lengths, force, speed, etc) - we could use some sort of fishing reels and a propellant (could be a spring or pneumatic), and the loading mechanism like a nerf gun or similar...
bottom line, it is doable, with a lot of imagination (i'm good at this :) ) and work, but we will have to discuss/negotiate the real price and time frame... (hope you agree...)
we could also discuss about prototyping of the physical model as a separate project, and i will be able to show you the gadget functioning
Regards
Bogdan
