Print the template, then lay it down on a flat surface. Cover with wax paper if you want to use it again. Glue all three fins in place with epoxy. While the epoxy is still wet, stand the rocket up in the center of the guide and sight down it to make sure the fins are perpendicular to the body. When you’re satisfied, put a little CA glue on each fin to hold it in place while the epoxy dries. When the epoxy is cured, add your fillets.
