I wanted a wall hanger for my Shaper Trace (Shaper Origin accessory) with a bit of storage for pens and the instructions. I suppose it's a bit perverse to not use Shaper design files for this, but 3D printing seemed more natural.
I split it into two parts so I wouldn't have to bother with supports. The hanger portion should be printed with the base down (hooks pointed away from the plate), and the storage should also be printed base downwards, i.e. opening away from the plate. The two parts are joined with a half-lap dovetail and a bit of CA glue to keep them from separating.
I just attached it to the wall with foam tape, but I also added a couple of counterbored holes that fit my #6 drywall screws if you prefer.
The Fusion 360 f3d file is included in case you want to resize anything or remix into something else.
