Wall-Mount Hook for Hailo Step Ladder

This hook mounts a Hailo Standing Step Ladder to a wall. I've designed it to hold the plastic top part of my Hailo L60 (PN: 8160-507) ladder - but probably will also fit others with a similar plastic part.

The part is massive and holds the weight of the ladder securely - even when printed in PLA.
The screw holes are 5 mm in diameter, so screws up to 4,5 mm should work with ease. Use countersunk screws.

I've included the FreeCAD file for your convenience.
