13mm NLT (Need Love Too) rocket UPDATED

thingiverse

I decided there wasn't enough love for 13mm 3D printed rockets so now we have the NLT, because 13mm's need love too! Designed to fly on 1/2A to A10 rocket motors. My test print weighs 1.38oz without a motor. Test flown twice so far on 1/2A motors in my backyard. Probably around 70ft high, no parachute needed on grass. Should be about 175ft on an A10. This design includes a motor retainer which snaps into place with a 60° rotation! Print with 0.8mm walls and 25% infill for everything, no supports anywhere! Body tube is 32mm and overall length with retainer is 182.6mm. A #4-40 screw will thread into the plastic to hold the nosecone to the coupler. *Tip*: Leave the motor in until it has cooled down. First flight I pulled the motor right out and the tube warped a little. I heated it up a touch with a heat gun and the motor went right in then cooled back round. 2nd flight I left the motor in and it was fine when it cooled. 8/3/19 - Update: Reduced logo height to improve printing quality. 9/19/19 - Update: Improved the motor tube design to reduce heat transfer. Also made some improvements to the coupler and retainer. There is now an 18mm version here! https://www.thingiverse.com/thing:3870711
