My Son wanted a Silly String gun printing for Halloween and found this on Thingiverse.

I left as the larger size in case we got different cans, but printed some adapter rings for the smaller cans.

I also made a cap to go over the trigger so it cant fall out, as it will be my Son using it.

My Son just wanted a glow in the dark nozzle, so I just made everything printable apart from the nozzle, then swapped filament and printed just the nozzle but with the settings as they were, so is possible to print all in one go.

Add a bring to the nozzle, as when it comes to printing the top of the long slots, it knocked off the bed without a brim.

Have fun.
