I designed this jig to make basic model rocket assembly easier for kids and adults. This jig is designed around the ESTES Wizard rocket, but probably works for others with balsa fins and a BT-20A body tube. You slide the body tube over the central holder, then the sets of fingers around the edge hold fins in any 90 degree vertical configuration you want for glue up. There are jigs you can buy, but this is a cheap print so you can print 20 for the price of buying one. The body tube can be held securely up to 2" or so from the base, so you can get creative on how you want to mount the fins.
