I made some of these for my cousin recently. After a few test runs it was easier to just make a handful of them at a time. Now I've got a bunch of left overs and wanted to see it anyone wanted a set. I made them at home on a custom built 3D printer. They will need painted unless you like the bright orange for some reason.
I've only got 1 set of orange launchers left. I got some black filament a few days ago and remade my set.
