Voron Raspberry Pi v2.1 Camera Mount

thingiverse

Simple mount for the Raspberry Pi v2.1 Camera for a Voron 2 printer. It should work equally well for most printers based on standard 20x20 extrusions with a Raspberry Pi running OctoPrint. Since the best view on the Voron 2 is from the front, but the doors need to remain openable, it easily rotates down for access, then rotates back up for printing and recording. You can also rotate the camera left to right and up and down to get the right angle, as well as to install it anywhere along the front bottom rail (except right in the middle). It could also be installed on the side of the frame if you like but the gantry will block much of the view. Parts required for assembly: * (2) 3mm x 6mm thumbscrews * (6) 3mm x 8mm cap head screw * (1) 3mm square nut (for the left-right rotation clamp) * (5) 3mm x 5mm (OD) x 3 or 4mm height thermal inserts * (2) 3mm hammer head t-nuts * (1) Raspberry Pi Camera v2.1 * (1) 24" Extended Raspberry Pi Camera Cable * Plastic glue (e.g. cyanoacrylate) To assemble: 1. Print as shown in the render to minimize supports. You will need supports for the arm and possibly a few other parts, but they are substantially minimized by this design. 2. Install the thermal inserts where shown by the red arrows in the render. Note that two of the insert holes are on the bottom of one of the pieces. 3. Connect the riser to the pivot with an 8mm screw inserted through the neck of the riser. 4. Connect the frame mount to the frame with 2 8mm screws and 2 hammer head t-nuts. These may be awkward to secure since the part can't support on the both sides of the frame due to the doors, but if you really snug it down, it should lock into place fairly well. 5. Connect the frame connector to the frame mount with 2 8mm screws. 6. Connect the pivot to the frame connector by inserting the bump side of the riser into the socket side of the frame connector, then secure the other side with the thumb screw. 7. Insert the nut into the riser slot and start an 8mm screw into it. Insert the arm into the riser. You can tighten the riser clamp now or later to fix the camera angle. 8. Connect the back of the camera case to the arm by inserting the bump side of the case into the socket side of the arm, then secure the other side with the thumb screw. 9. Feed the camera cable through the bottom slot of the frame mount and through one of the holes in the Voron's skirt. Feed the other end up through the slot in the arm and into the slot on the bottom of the camera case. 10. Make sure the Pi is powered off (or unplugged), then connect the camera ribbon to the Raspberry Pi and the camera, then place the camera into the case, aligning the pegs with the holes in the camera. 11. Don't attach the front of the camera case yet. Stop and test everything to make sure you're happy with how everything is working and that the Pi is detecting the camera. If not, deal with that first. 12. Once you're happy, affix the front of the camera case to the rear with a few small drops of the plastic glue in the groove in the corners. Don't overdo the glue... if you ever need to remove the camera, you'll just pry this apart and break the little glue dots. (I considered making this a screw on part but I was trying to keep it small and simple). That's it! Now you just need to focus the camera and adjust it to where you get the best view. Happy printing!
