HDMI And USB-C Plug-Through Cable Bulkhead
This screw-on bulkhead plate lets an HDMI or USB-C cable with the plug already fitted pass through a project-box wall. Cut a 30 x 16 mm window in the enclosure and push the plug through. Slide the cable sideways into the 8 mm slot (cables up to about 7.5 mm OD), then fix the 64 x 44 x 3 mm plate over the window with four M3 screws on a 52 x 32 mm pattern. The half-pipe saddle on the plate is 23 mm tall and has two 4 mm zip-tie grooves that hold the cable, so a tug on the cable doesn't pull on the port inside.
USB-C TP4056 Charge Port Retrofit Bezel
A panel bezel for adding USB-C charging to an old flashlight, boombox or cordless tool. You bolt it behind a hole in the case with two M3 screws on a 43 mm pitch. A TP4056 USB-C charger board (up to 22 mm wide and 29 mm long) stands against the backer wall and is held by two zip ties. The board's connector end sits over a 12.5 x 7 mm plug window in the 2.4 mm flange, and an M3 self-tapping screw in the top tab backs the board so it can't be pushed in when you plug in the cable.
