I have designed a 3D model of the Estes PRP-1G fin can that was used on kits such as the Estes Challenger-1 and the Kadet among several. I have included several variations with a few more in the works.

Here is a list of model rocket kits that have used this fin can.
Kit# 1235, No. 2 Sky Writer #2
Kit# 1260, No. 2 Estes Sky Writer #2 (same kit, different package)
Kit# 1328, Kadet
Kit# 1333, Scorpion (used 2 fin units) (early production kits)
Kit# 1416, Challenger-1 (starter set)
Kit# 1418, Star Trek (starter set)
Kit# 1420, Star Wars Proton Torpedo (starter set)
Kit# 1438, Dune: The Guild Heighliner (starter set)
Kit# 1447, America (starter set)
Kit# 1993, Lancer
Kit# 2026, Athena
Kit# 2042, America

I have this one. Just up-scaled it to BT-60, but haven't printed it yet.

Here is a pic of the print in BT-60. Not sure if it is going to be an up-scale Challenger or print another and build a second up-scale Scorpion. There is a slight lip at the front of the fin unit, I will have use putty to smooth the transition to the tube, or use a thicker tube.
