Giá đỡ lắp đặt cho bộ nguồn USB PD Trung Quốc

Many USB PD power supplies from China nowadays come in cases that are built from a 50x20mm aluminum extrusion (see for example here) and have front/back plates, that are attached with M2 screws in a rectangular pattern (45x15mm). I built mounting brackets for these.

Three versions are included here:

• open bracket (just a "ring" around the aluminum extrusion)

• bracket with end stop - leaves almost the complete end plate accessible for plugs

• bracket with end stop and holes for the M2 screws used to attach the front and back plates (maybe replace the original screws with longer ones) - this has a slightly smaller opening, please verify if all plugs still fit.

This is a very simple print. Please use a somewhat heat resistant filament (PETG). The manufacturers of these power supplies have chosen aluminum for the case of these units for a reason (heat dissipation).
