This is a redesign of the stock shelf portion of this product:

The main modification is that, in my bathroom, the outlet is very close to the adjacent wall\medicine cabinet so I offset the shelf from mount to slide it over.

Printed with Prusa MINI+

Nozzle: .4 mm

Layer Size: .20mm

Filament: PLA

Supports: Yes (recommend printing with the “lip” flat on the bed and supports underneath the mounting arms).
