4" PVC Tube Mounts- use to mount lipo battery tubes in backpack

These mounts secure my battery tubes inside a backpack, but they can be adapted to mount to a number of surfaces. Nut traps are sized for 8-32, but M5 should work. Mounts are designed to be secured to 2" x 1/8" aluminum strips using standard (1/8") rivets. The tube is held in place via 2" velcro straps- I got mine from mcmaster.
There is a single pack version and a double pack version. The double pack version requires post print bonding, see pics. I've included the sketchup files, happy printing!
