Nano Bracket - Bike Tube Strap Bracket

prusaprinters

Edit September 2023: I added the STEP file because someone requested it. This is an older model and I've learned a lot since, but it seems like it still works for people so I'll hold off on a redesign for now.—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.Print SettingsPrinter:Matterhackers Pulse XEResolution: 200Infill:20Filament:Matterhackers NylonXBlack Notes: Printed at 0.1 layer height, 20% infill, with supports. For maximum strength I've printed this flipped flat on its back, but to get a nicer outside finish I printed a couple on their side and they were more than strong enough.I used Matterhackers' carbon fibre NylonX filament and it's very stiff, especially once mounted on the bike.How I Designed ThisDesigned by someone who doesn't know what they're doing in Fusion 360. Category: Sport & Outdoors
