This is a template model for my Toroidal Launcher design that can be remixed into any attachment you'd like! The template includes the interior thread profile along with a copy of the hexagon mesh screen used on the bottom of the housing; when combined with the original launcher design the result is a simple two-stage handheld gearbox. The hexagon screen is 2.5mm thick and can be easily split from the threads along the Z-axis for remixing.
