I am happy to present a 3 x 4 gridfinity adapter for the Pinepower 120W power supply! This file is designed to work with the 123mm x 115mm x 48mm version of the power supply.  The adapter retains adequate ventilation and access to the power switch in the back. The qi charger remains accessible, and the surface is extended to give your phone a larger platform to rest. 

Print with supports. The base of the power supply is a little wider than the top, so be careful inserting the power supply into the print.
