Modular Fin Jig

This is a modular estes model rocket fin jig. This current file is for a 4 in outside and the modular pieces make a 25mm inside hole. This can be changed if you download it and put it into 3D software. Or you can send me requests via Thingaverse messages or in the comments. Furthermore, you can request different fin widths and heights, etc. If you don't have a 3D-Printer go here: https://www.etsy.com/listing/1602004759/modular-fin-jig-modular-fin-putter-onner
