Móc treo bánh xe đạp lên trần (openSCAD, tham số)

I wanted to use the space in my garage as efficient as possible.
Spare bicycle wheels always stand in the way and the wall is already occupied with other stuff.
So to get rid of the axel standing out, I thought to plant it between the beams.

Use 2 hooks, align them well and you can slide the wheel in and out of the hooks, so you do not need to screw anything to get the out or store them again.

The hook standard has 2 screw heads sunken in, with an extra hole to be able to screw the "inner" screw into the beam.

The openSCAD file is attached so anyone is able to change the sizes to their liking.
The fillet is added to make the construction somewhat stronger. The openSCAD file is optimized to not calculate the fillet always (on every preview), but only makes it "neat" when it is rendering it for non-preview. So the preview fillet does not look as smooth as the actual render.
The rounded inner corners are based on a Thingiverse Tutorial: https://www.thingiverse.com/thing:966752

Print settings I used (but can be anything)
