BT-55 Fin Can for 24mm Motors

thingiverse

I set out to make a lightweight fin can for a BT-55 sized body tube that could fit an E sized motor that was also easy to print. Printed in Anycubic Clear Blue resin, it came out at 38.51 grams, with the motor only 109.90 grams. The neck is 13.5mm long with holes cut out to save on weight while still being strong, The motor mount tube also has holes cutout of it for the same purpose. This is very light, so make sure you manage your center of pressure by using a longer body tube or make your nosecone heavy enough. Rocket flew very stable for me using an 18" body tube and a printed nosecone.
