I needed a wall-mounted shelf that securely holds a tablet on the wall above a treadmill. The treadmill I have has a slot for a phone or tablet, but using it blocks the display. This also lets me look up rather than down at the treadmill.

Notes

The best orientation for printing this shelf is with it lying on its "back," which is the side mounted to the wall. The bridge that forms the front lip isn't large, so supports may not be necessary for some printers.
