Handheld Trigger Grip - Model Rocket Launcher

thingiverse

I wanted a simple model rocket launch controller that would let me use a small LiPo with some safety protections. Wraps up nice and clean and small with wire around grip and alligator clip leads clipped onto either side of the flip trigger cover. Has a 7mm hole for a momentary push-button switch. I fit a small 2s high-amp drone LiPo in the grip (I used a RDQ 525 mAh 80c 68.2x17.2x13.9mm). Takes some creativity and correct length lead to switch (just past bottom of grip works). V2 EDIT: Small modification so users can add a wire clip to lock trigger guard cover down to protect / block switch (also made trigger guard cover more solid in front so that button cannot be depressed accidentally with small fingers or other objects). I also made the grip 3mm larger to eliminate the cut throughs. V3 EDIT: Made the battery door a bit larger to help user fit battery and wires in grip.
