Model Rocket Kit

<p>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!</p> <p>I recommend using a cardboard body tube, but if you are determined to print your own or want to try a multi-stage rocket, check out this remix: <a href="https://www.thingiverse.com/thing:4423394">https://www.thingiverse.com/thing:4423394</a></p> <p>Based loosely on the Estes <a href="https://www.amazon.com?linkCode=ll2&amp;tag=thingiverse09-20&amp;linkId=e4759bff1fa9a55a0f897d801ce2d765&amp;language=en_US&amp;ref_=as_li_ss_tl">Amazon</a>.</p> <p>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.</p> <p>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.</p> <p>You can also print 2x 18_mm_motor_adapter and use 18mm motors like Estes C6-3.</p> <p>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.</p> <p>Here's a video of the rocket blasting into the sky in slow motion: <a href="https://www.youtube.com/watch?v=r5LMzHydy4g">https://www.youtube.com/watch?v=r5LMzHydy4g</a></p> <h3>Print Settings</h3> <p><strong>Printer Brand:</strong></p> <p>MakerBot</p> <p class="detail-setting printer"><strong>Printer: </strong> <div><p>MakerBot Replicator 2X</p></div> <p><strong>Supports:</strong></p> <p>No</p> <p class="detail-setting resolution"><strong>Resolution: </strong> <div><p>0.2mm</p></div> <p><strong>Infill:</strong></p> <p>0%</p> <p><br/> <p class="detail-setting notes"><strong>Notes: </strong></p> </p><div><p>Designed with ABS shrinkage in mind. You may need to scale up slightly for PLA. I'm not sure.</p> Use 1.6mm wall/top/bottom thickness. The models do not require infill or supports. You may need to rotate them. <p>Try turning gap fill off if you get weird results on certain layers on nose cones, especially.</p> <h3>Instructions</h3> <ol> <li>Choose your fins! (one of base_*.stl)</li> </ol> <p>If your goal is a very stable flight, maybe don't pick the forward swept fins. 2. Choose your nose cone! (one of nosecone_*.stl)</p> <p>If your goal is a very stable flight, maybe don't pick the spearhead. 3. Print 24mm_motor_cap.stl 4. (Optional for 18mm motors) Print 2x 18_mm_motor_adapter.stl 5. Glue base to body tube 6. Sand nosecone to fit loosely in body tube 7. Add a recovery system.</p> <p>I use a parachute. There's a loop for mounting a shock cord on base_*.stl.</p> <p>There are plenty of excellent guides on the net for building model rocket recovery systems. 8. Install a motor</p> <p>24mm? D12-5, C11-5.</p> <p>18mm? C6-5, C6-3 9. Launch your rocket!</p> </div></p></p> Category: Hobby
