Wallmount System universal attachable hook (Allit StorePlus)

This is a universal hook that can be mounted to other holder-thingys, or anything really, to make them compatible with my [Wall mounting and storage system](https://www.thingiverse.com/thing:6082906) (like Allit StorePlus and many others). You can either use two countersunk screws of up to 3.5mm diameter, or you use ca-glue/superglue to fix it to other 3d printed parts. For heavier loads, I recommend adding extra supports to your holders in order to distribute the load better. See my example photos. (last three have makeshift supports out of pieces of wood, to offload downward forces against the wall.
Update: there's a new version, that also includes a stop. This will prevent unintentional un-hooking of light holders when you pick something up. Haven't printed it yet, tell me how it works!

Printing:
For stability reasons and to avoid supports, it should be printed standing upright, so I recommend using brims to secure adhesion.
Prints best on 0.6mm nozzle with 0.8mm extrusion wi
