This remix of http://www.thingiverse.com/thing:1637227 that adds a mounting bracket for the rear holes that already exist above the control box of a Lulzbot Mini. I'm using Octoprint to control my Mini. So far, the Pi has just been dangled down next to the printer. I wanted to mount it in a case to the side of the printer and clean things up.
First problem was the case itself. Most of the Pi cases I found were either tricky to print accurately or broke easily. This case was pretty easy to print, snaps together nicely (no screws, yay!), has vent holes and GPIO access. Nice case.
Second trick was mounting. Most cases I saw for the Mini had mount brackets for the front of the Lulbot Mini, which I did not want because then the USB cable connectors stuck out past the frame of the printer and were sitting ducks to get hit. So I measured up the rear holes and made a bracket for it. Added the mounting bracket to the side of the bottom, and we have a winner for the Lulzbot mini!
Pix coming soon.
I did 20. Up to you, but 100 might be a good idea.
