This device is intended to be attached to a backpack so you can carry quads on it. It was designed to be used for my personal backpack which is a "hard shell" style kind of backpack, it works great. Total of 8 hole if your carrying something heavy, but for a normal quad you only need 4 screws, or if you would by any chance would break a hole.
Each object (front and back plate) is 0,4cm or 40mm ( 80mm total if using back and front plate) thick so you can get an idea of what length of screws that is needed.
Uses M3 (holes are 3mm wide)
Print in any material, designed to be printed in PETG/PLA (tolarance)
Print: 0.2mm 10% infill, 4 outside perimeters as well as 4 for the top and bottom (feel free to experiment with other perimeters)
Nozel: 0.4mm (standard)
When installing, place velcro strap in place before attaching to backpack.
Back plate added upon request.
Place some heat-shrink on the bolts or screws on the inside to avoid getting cut by the metal when inserting your hand into the backpack to look for things!
