PiCam Print Bed Mount

thingiverse

Having viewed several camera mounts for the Raspberry Pi camera (V2.1), I decided to take on the challenge of designing my own. My goal was to create one that would securely attach to the print bed for a more stable timelapse image of prints. The mount attaches to the bed via a U-shaped bracket and threaded wingnut. I have it clamped to the plate that carries the heated print bed on an Ender 3, which has been modified with an EZABL and without springs or adjusting nuts for a fixed position. However, it can also be clamped directly to the bed. To accommodate glass plates like mine, I've left enough clearance in the clamp. You may need to adjust the camera's focus to account for the short distance to the print area. I used a wrench (https://www.thingiverse.com/thing:1570865) to fine-tune the lens. The U Bracket is secured to the arm with a M4 bolt, nut, and spring washer - see image no. 3. Print Settings: Resolution: 0.15mm Speed: 50mm/s Material: PLA Nozzle Temperature: 205° (210° on the first layer) Bed Temperature: 60° Infill: 30% 5mm Brim on all parts except the arm. Update: I created an additional bracket, known as the extrusion bracket, which fits onto the top aluminum extrusion of the Ender 3. This allows the arm and camera assembly to be re-positioned to view the print bed from above. Another Update: I've added a recess in the arm for the nut, so now only a 12mm long bolt is required.
