I modified an existing raspberry pi camera case design to hook to the two screw holes in the top of the lulzbot mini. to keep the print flat, I experimented with a dovetail attached mount rather than printing the mount as a single object. A little fiddling with a sharp knife post print was needed to make it come together. The 3mm holes were tapped with a M3x0.5 tap so that the existing lulzbot screws would hold the camera dovetail piece directly.
This thing was made with Tinkercad. Edit it online https://www.tinkercad.com/things/jTpye3jvpVx
Version 2 and onwards of this thing was made in Autodesk Fusion 360: http://a360.co/1nTJUIQ
The STL files were all laid out for printing in a single job in tinkercad at the original tinkercad address.
