Fin Cone fin jig

thingiverse

A modified (and better version) of Just Another Fin Jig (https://www.thingiverse.com/thing:3187888). Turned the fin slice into a cone instead of a flat circle. "He's intelligent, but not experienced. His pattern indicates two dimensional thinking" - Mr. Spock. It gives more area to hold the fin, and works much better for fins attached above the bottom of the body tube. Putting both 3 and 4 fin slots made it too weak and easy to break. Just print whichever one you need. The extra slot is for motor retainer. Made a couple of prints and tweaks. This version seems pretty solid. Just print as shown, it printed fine no supports required. .12mm height.
