This is my 6th revision of my Potato/Nerf cannon. The main body is printed in any solid plastic. I've found PLA and PETG work just fine. I printed the Gaskets in TPU 85A, but I will be releasing a different optional cap that doesn't use gaskets, so this can be available to more people. You can use practically any flammable to power it. 99% Isopropyl alcohol works well. I've also used hairspray, and it works well. I've noticed a lot of these types of models recently, and I've been working on this project in private for over a year now, so it frustrated me that I hadn't posted something, but I'm confident my cannon works better than any other out there.

Keep in mind the seal is made to be tight; it will take some working in to be easy to use.

You will need a Basic grill sparker. You can find it here Grill Sparker. I ordered one on AliExpress for a couple of dollars, but as long as the spark tip is that design, it will work.
