WebShooter prototype in the making

This is just a prototype and it is not finished yet. It still requires an arm brace, a battery for the solenoid valve, and a switch. Also a connector between the solenoid valve and ball gas valve. Any ideas on how to make it smaller but increase the volume of the fluid cartridge? It will only give me one shot of 5.5m long, 2mm thick strand of web fluid. Future design will be much better and more compact but I think it's a good start for what's locally available. Here's the webshooter website, but it wasn't made by me, I'm just a member:
