Last night I printed one of the lower fins. Took about 2 and a half hours. Leo provided 2 versions of the upper and lower fins, one version is larger for flight like the Estes fins, and the other is scale. I'm printing the larger for the lower fins, although I might print the smaller scale fins for the the upper to help stability. The weight of the fin is 10 grams. 5 more to go!
