Hey guys! Thanks for checking out the video! Protostrap was born out of sheer boredom while my kids were at a four-hour-a-day spring break swim camp. Picture me just sitting there with my sketchbook, trying to think of ways to avoid making more stuff in China LOL If you've got a 3D printer, give it a try! Takes some getting use to, but it works. It's still super lightweight too! Use two straps if necessary.

1) Protostrap comes in two parts. Strap and Loop.

PROTOSTRAP L
3) Protostrap L is untested and unproven. Was designed for 4000mah L-ions + to fit future LR frames. Use at your own risk. I may revise in the future to be wider and thicker.

WIDE PROTOSTRAP P5G
4) Wide Protostrap P5G is designed for a future protofpv tank frame, but go ahead and try it. :) It is untested and unproven. Was designed for most 6S 1000 ~ 1500mah. Extra wide so you don’t need to use two straps! I may revise in the future, the hole in the middle is too long.

COLD AND WARM CLIMATES
5) TPU gets stiffer in cold days or more elasticy during warm days, so just make sure it's always nice and tight. Don't assume and count on using the same hole in the strap.

FLOW RATE
6) Besides having good print and temp settings, I found the most important setting for protostrap is to set your flow rate to 110%. This will make everything thicker and stronger.
