USB Add-A-Port Panel mount

thingiverse

Add a USB port anywhere. I'm shocked I couldn't find an STL available. A little electronics knowledge is needed to locate and tap the DC voltage to power the USB port safely. Always unplug before working on anything. I won't detail every step involved, assuming your requirements are different from mine. If you're unsure, maybe you shouldn't be doing it. You can get hurt or burn down your house. A marking template for the mounting holes is included. The pictures show an old 2.1 PC speaker system and Android phone with a bad battery, repurposed as an internet radio/DLNA audio receiver that now only needs one plug in my power strip. Print Settings: Printer: CR-7 Rafts: Doesn't Matter Supports: No Resolution: .3mm Infill: 20% any Post-Printing: The USB cutout should be pretty tight to avoid the glue from seeping out. It will probably need some finishing to fit the face of the connector properly. How I Designed This: Simple FreeCad design Custom Section Presented as "Proof of concept" Tape around the connector or the hot glue will ooze inside the connector. Fit the connector flush with the front of the panel. Fill the space around the connector with hot glue. Find points on the board to supply power to the DC-DC regulator or wire an old 5-volt adapter to the mains voltage and wire the 5-volt output directly to the female USB. Always unplug before working on anything. Make sure all mains connections are well insulated. Adjust the regulator pot for 5 volts; I always try to stay around 5.1 volts. Some devices won't charge below that. If you're positive your device can supply 2A or more, the center two pins can be shorted together to trigger high-speed charging. I probably should add a separate fuse. If you don't get it... maybe you shouldn't be doing it. You CAN get hurt, burn down your house... LASTLY, DON'T BLAME ME; I'M JUST PUTTING IT OUT THERE.
