Hey everyone, I created a mustard gun to shoot mustard on your targets. It can presumably work with other liquids too, like water.
I printed all parts with PLA except for the "Gun Innards" and the "Plunger." These two parts require the Formlabs Durable resin to make the parts liquid tight, and also have enough flex in them to function properly. Disclaimer: it's hard to get it to work and to keep working. If you do want to make the attempt, download my Gun_Innards.form file to get the proper internal support structure and orientation for proper printing. You will need a syringe to push alcohol through the system to clean out any remaining resin. Once it's thoroughly flushed, don't put it in the sun or under any UV cure baths. Keep it from hardening any further. You may need to run alcohol through it before each refill to keep things loose. Actually I would just give up now
Have fun!
