Rocket Fillet Tool

Simple tool to shape fillets on rockets without tape.
v2 has a 45 degree chamfer on the fillet edge to help push excess epoxy down into the fillet as you draw it across the joint. It's a minor difference, but should result in a better fillet.

v3 is a more universal tool with a holder - flat edge for the fin side with a chamfered circle for the fillet. Numbers on the tools are fillet radius.

Customizable OpenSCAD in v1 and v2. Main variables:

Rocket outer diameter
Fin thickness
Fillet radius
Tool thickness
