This is an accessory for the USB type B socket on a Lulzbot Mini 3D printer. After a lot of connecting and de-connecting cables from mine, the socket's solder points weakened and the port ripped straight out of the Rambo control board, so I designed this insert to prevent that problem (It is possible to replace that USB port, but it sure was a hassle for me). Print with the "pyramid" upside-down, I did mine with a brim to ensure a nice bond to the bed. When installing, just slide the insert into the air gap between the port and the metal enclosure, with the open side facing the right. Enjoy!
