Model Rocket Kit

thingiverse

A model rocket kit for Estes BT-55 body tubes. Choose from 4 nose cones and 3 fin sets. Or take the solidworks files and make your own! Based loosely on the Estes Amazon. Wall thickness is 1.6mm, so best printed with a 0.4mm nozzle. base_swept_12.stl is an experimental 1.2mm wall thickness version. This rocket flew beautifully with Estes D12-5, but it should work with other 24x70mm motors like Estes C11. See the Open Rocket simulation file. You can also print 2x 18_mm_motor_adapter and use 18mm motors like Estes C6-3. There's a shock cord mount near the bottom of base_*.stl. If you mount your shock cord here, make sure it's made of kevlar or some other very heat resistant material. Here's a video of the rocket blasting into the sky in slow motion: https://www.youtube.com/watch?v=r5LMzHydy4g Print Settings Printer Brand: MakerBot Printer: MakerBot Replicator 2X Rafts: No Supports: No Resolution: 0.2mm Infill: 100% Notes: Designed for ABS. You may need to scale up slightly for PLA. I'm not sure. Instructions Choose your fins! (one of base_*.stl) Choose your nose cone! (one of nosecone_*.stl) Print 24mm_motor_cap.stl (Optional for 18mm motors) Print 2x 18_mm_motor_adapter.stl Glue base to body tube Sand nosecone to fit loosely in body tube Add a recovery system. I use a parachute. There's a loop for mounting a shock cord on base_*.stl. There are plenty of excellent guides on the net for building model rocket recovery systems. Install a motor 24mm? D12-5, C11-5. 18mm? C6-5, C6-3 Launch your rocket!
