I'm using OctoPrint to run my MakerGear M2. I wanted to be able to mount the Pi in a position that gives a good view of the part so that I could remotely monitor it. The mounts that I found on Thingiverse were fairly large or tended to hold the camera in a bad position or both. This mount is very simple, just two small pieces so that it prints quickly and it works with readily available 1/4" LocLine (buy the genuine stuff, not the Asian ripoff). The Pi/Camera can be easily positioned in any orientation and it doesn't wiggle around. The base piece is held to the frame of the MakerGear with a single M3 screw, one washer and one Nylok nut. The VESA mount is secured to the RasPi case with (4) 3mm screws and Nylok nuts. For best results print in ABS, PLA is a little too slippery and the mount tends to wander. The nut recesses are intentionally a little snug so that the nuts don't fall out. For the VESA part, just give each a gentle squeeze with pliers to seat them. For the other piece, use the M3 screw with washer to draw then nut into its hole. Then gently remove the screw without displacing the nut. Snap it onto the locline then position on machine and tighten nut without knocking it out of its hole. It's very easy, more trouble to describe than to do. ENJOY. Works with these stunningly beautiful Raspi Cases: http://www.thingiverse.com/thing:922740 http://www.thingiverse.com/thing:608169 Genuine LocLine is available for cheap on Amazon if you don't have any: http://www.amazon.com/gp/product/B006R9O3HE?psc=1&redirect=true&ref_=oh_aui_detailpage_o08_s00 These pliers make it easier to assembly/disassemble but aren't really necessary if you have enough hand-strength to open tight peanut butter jars. http://www.amazon.com/gp/product/B006R9OT8M?psc=1&redirect=true&ref_=oh_aui_detailpage_o08_s00
