Newbi, Proton Pack Wand,Gun,Thrower

Hello, first off, this is a great website, I have wanted to build my own proton pack since I was a kid and seeing ghostbusters. I have now got round to doing so. I have got some great plans, and ideas from everyone on this site and have been a huge help. I have a 3d Printer so can print some items using STL files. I am still learning with solidworks so I have a long way to go.

I really need some help with the wand, gun, thrower. the dimensions would be really helpful. I am in the UK so inch’s don’t covert easier here. If anyone have the main section in a SLT form and would not mind sending me a copy it would be really, really helpful. I am not selling this on, just making it for myself.

Please help.
