Estes Goblin - BT60/29mm Motor Builder's Kit

thingiverse

Builder's kit for upscaled Estes Goblin with BT-60 tubes, 29mm motor mount and profiled fins. Centering rings have pass-through for kevlar cord so it can be replaced/inspected easily. Nosecone designed with deeper location to get shock cord attached....may change it once I print it and see how it is. Also has blocking ring in the tip for holding in epoxied nose weight without dowels or other tricks. A note on printing the fins. Rotate so the leading edge is parallel to the printer bed but still on top. Print with supports. This should make for the strongest orientation. If printed with the tab on the bed, then it's easy to snap them off along the body tube. 4/30/23 - Added thicker-walled version of the fin can. The original is in the files, but awful thin, to where faster descent speeds might prove detrimental to its integrity. 5/3/23 - Have printed everything. Centering rings are snug, so a tiny bit of sanding may help. Epoxy should help get things into place. Also added a 29mm motor retainer based on this https://www.thingiverse.com/thing:882815 - slimmed down a bit to be no wider than the BT60 tube. 7/5 - Added solid fin can that can be printed in one shot. Use supports.
