MTB - Ceiling hook - saddle

I've desgined a hook strong enough to hold a mountainbike to the ceiling. It's desgined to be attached to a wooden beam. There are two holes in the bottom for 4 mm screws and for the main weight carrying there are three holes for 5 mm screws on the base plate. It is advised to use washers (for weight distributing) when screwing the three 5 mm screws.

As shown in the image it is designed with enough room to hold by the saddle (with the center point of gravity in mind. You can just simply put it there without any strapping of ropes or bolts.

I've also added the F3D-file so you can adjust it according you own ceiling and/or mountainbike.
