Summary

Mounting bracket for small PCB type USB B ports.

I made this as I couldn't find a USB B female port suited for mounting on my mendelmax. Seriously, I looked everywhere for a plug that would suit the mounting holes provided.

Instructions

parts required:

four 3mm (of suitable length) bolts for mounting, with nuts and washers
USB B PC mount socket (e.g. http://www.jaycar.com.au/productView.asp?ID=PS0920), with mounting PCB.

The USB B port is soldered onto the small PCB that was provided with it, along with a 4x2.54mm set of male pins, for connecting the cable from the control board (I used a RUMBA, which has suitable pins for connecting to the USB).

The PCB is mounted on the bracket. using two of the bolts.

The bracket is mounted on your printer using the other two 3mm bolts.

Connect the to the usb port to the printer board using a 4 pin female-female cable (may require some testing to get the pin order correct, if you don't have the schematics for your plug and board).
