Bike Hook

I made this bike hook in order to find a space-saving solution to store all of my family's bicycles.

Since I didn't want to drill 1-2 holes for each bike on my walls/ceiling, I exploited an old clothes hanger and designed this "double hook" to turn it into a bike rack.
The design is quite robust, it's been working with 15 kg bikes for 4 months so far and there are no signs of weakening. I'd like to know how it works with heavier bikes, if you find its limit please tell me! The size is big enough to easily handle 29" x 2.3 MTB wheels (and probably bigger sizes).

I split it in 2 pieces, so you can print it in a typical 200 x 200 mm build plate, with less risk of losing a lot of time and filament if something goes wrong during the print. Moreover, if the lower part wears out, you can print just that, keeping the upper part, or you can customize just your upper or lower part if you have different needs. The 2 parts can be fixed together using 3 M8x20 screws and nuts.
