The file 'Nano Bracket – Bike Tube Strap Bracket 3D Printer Model' is (stl) file type, size is 268.7KB.
Made a simple bracket for strapping a tube to a mountain bike. It mounts to bottle cage bosses the standard 64mm apart, and uses a 1/2" wide Voile Nano strap. I've found the 9" length to be perfect for most MTB tubes.
The bracket works best on the new generation of bikes with a mounting point under the toptube. It's curved and inset to match up with most toptubes; see photos for how it fits on a Raaw Madonna V2 enduro bike.
Printed with NylonX and 20% infill it weighs about 5g, way lighter than commercial tube strap brackets. With the Nano strap (9g) and the ultralight Aerothan 29er tube it all weighs 111g. The combination of a regular tube, bracket, and strap is nearly 300g, so this is some cheap, easy weight savings.
