UPDATE 20.12.2017: I finally printed this, updated design to use less material. This can only print with support now. Used 3 shells (1.2 mm) and 10% infill.

This is a bicycle wall mounting hook. It catches bike pedal, and aligns the bike at 30° to the wall. With this you can hang up to 3 bikes on the wall, all reachable by person of average height. The inspiration for this was taken from https://www.kickstarter.com/projects/1343076509/dahanger-dan-bike-hook-life-is-too-short-for-just Attached with two screws.

• This is a long print :(
• It takes 150-200 grams of material
• I think it should be strong enough for a road bike (~9 kg)
• The strength of the part can be increased with more shells and denser infill

On the photo, a prototype 1:3, it feels quite strong, i've manage to lift my bike with it.

Added a 'lite' version with ~30% less material.

Any comments particularly ideas about making it lighter and stronger are welcome!
