This is a simple wall-mounted shelf I built to support a wireless router installed in an unfinished cubbyhole. It would be suitable for small speakers or something similar. It is designed to be anchored in a single vertical line, such as a wall stud. It has countersunk holes for pan head screws.

Notes

The best orientation for printing this shelf is with it lying on its "back," which is the side mounted to the wall. Supports are used to support the rounded edges and cable passthrough. The bridge isn't large, so these may not be necessary for some printers.

For heavier loads, increase the infill. I used PLA for this print, but it's installed indoors in a reasonably cool area. PETG or ABS would be better in a harsh environment.
