This sale includes the STL files for all the 3D printed parts as well as fin templates to build a semi-scale model of the English Electric Thunderbird Surface to Air Missile (SAM): https://en.wikipedia.org/wiki/Thunderbird_(missile) -- I am asking $8.50 for the STL files. Please message me and I will share paypal info and will send a .Zip file with STLs and some build notes once payment comes through.
You can see parts included in STL files in picture #1 as well as built model in picture 2-3 and . You will need to provide body tubes, shock chord, parachute, and 18mm engine if you want to launch this (just need the body tubes if you want a static model). Model flies great on C6-3 or C5-3 engines (launch pictures in picture 4-5). Model is 17.5" tall and gets tons of compliments online and in real life. The booster side tubes are dummies in this model. You can see the first few seconds of my maiden launch here (I was alone so did not follow rocket well at all):
I made / built lots of versions to get to this fine-tuned design. Boat tail includes built in quarter-turn locking engine retainer (see picture 6), large side booster fins mount through booster tubes into slots in 3D design to make them stronger, rear small fins mount through boat tail and hold bracket in place, holes included inside boat tail to mount shock chord via 2x redundant Kevlar lines tied around engine mount (or can be glued to body tube in the standard Estes fashion). Uses stock cardboard body tubes to keep weight down: 1x BT 55 Center Tube + 4x BT20 Tubes (boosters) -- booster tubes should be 9" long and main body tube should be 9.5" long. Some build pics #6 and #7 below and a prototype pic in the last picture.
Includes options for beveled or unbeveled T-fin booster fin tips as well as 1.5 mm fins (I use 1.5mm basswood), 2mm, or 2 + 2.5 mm fins (2.5mm for large fins, 2mm for smaller). Shock chord attachment point for nose cone is separate so you can add weight to nose cone (I did not add any but you may want to depending on your build and flight conditions). My fully built / painted model w/ parachute, shock chord, etc... (no motor) weighs 138 grams.
