V1 of a printable and modular 38mm motor minimum diameter high powered rocket that is simulated to be flyable on anything from Estes D12 Motors to biggest 38mm (you'll need to print additional lower body tubes for longer motors). First flight on estes E12-4 w/altimeter and telemetry module: <iframe width="344" height="611" src="https://www.youtube.com/embed/yqf7ZwopSxo" title="3d Printed medium power #rocket #modelrocket onboard and from ground" frameborder="0" allow="accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share" allowfullscreen></iframe> Includes threaded nosecone ebay (intending for chute release recovery) designed for eggtimer [quantum altimeter](http://eggtimerrocketry.com/eggtimer-quantum/), and [eggtimer telemetry module](http://eggtimerrocketry.com/eggtimer-telemetry-faqs/) beneath quantum so that telemetry module antenna fits within nose cone Printed the green parts in PLA+ - parts sized to fit a printer with a 175mm Z range You will need a heavy duty LOC 38mm MMT to build this rocket - this is used to insulate the PLA from the heat of the rocket motor: [link to purchase tube](https://www.erockets.biz/loc-precision-body-tube-motor-tube-1-58-38mm-x-17-to-20-1pk-loc-bt-1-58x20/) Printing notes: 1. it probably makes sense to print the fin can and recovery tube in higher strength PLA or other plastic like PETG or ABS 1. all parts can be printed w/o support except the AV bay - it will need to be printed w/ touching support to support the battery box if printed vertically (may redesign to add fillet and avoid the support in the future) In addition to all the printed parts you will need the following to complete the model: 1. LOC precision heavy duty cardboard 38mmt 1. recovery kevlar string probably 150 lb is ok? 1. nomex chute protector 1. 15" chute (simulates to acceptable decent rate) 1. M6 eye nut and m6x4mm-ish bolt for nose cone and chute attachment Optional 1. chute release for high power motors/altitude 1. eggtimer [quantum altimeter](http://eggtimerrocketry.com/eggtimer-quantum/), , [m3 nylon hardware with standoffs] 1. [eggtimer telemetry module](http://eggtimerrocketry.com/eggtimer-telemetry-faqs/) and receiver 1. [this size 2s lipo battery](https://www.amazon.com/gp/product/B0719TD5BT/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1) 1. 38 to 24mm MMT adapter for smaller motors Build and fly at your own risk designer not liable for your use of these designs and follow the NAR safety code for model rocketry.
