Silly String Sprayer

This is a silly string web shooter I made. My son is spider-man mad so i though I would model him a web shooter. I know you can buy one, but it;s a fair amount of money and the re-fills are a rip off, that's why I designed this one to work with Poundland silly string.

It fires a good stream and he loves it so it was a success in my book.

I have tested it with Poundland silly string and The Entertainer (a toy shop in the UK) and it works with both. The diameter of the can is 45mm, with the top of the can (the metal band the dome clips to) measuring in at a 43mm diameter.

::EDIT::
Added SprayCap.stl this will slot over the spray nozzel so it has a better contact with the tirgger (trigger1) so it should not get stuck when firing
