Additional hook for IKEA Trotten (fixed version)

This is an additional hook to be mounted on an IKEA Trotten desk (the fixed version, not the height adjustable). It's made to be placed on the side, between the legs of the desk, using the two big sleeve screws from underneath. 

The design is optimized to be printed without support if placed laying flat on the big rib on the back of the hook (see pictures and gcode). 

I printed it in Prusa's default 0,20mm QUALITY profile, with default 15% infill and the default infill pattern in Prusament PLA and so far it holds even my quiet heavy bag very well.
