I was looking for a few things for my camera mount:
- Close enough to the print to be able to distinguish the details
- To go up with the print head
- Robust enough not to vibrate and blur the image
- Easy to install without screws or accessories.
I found the design of lab27 to be very good for that, so I modified it a bit to work with the Ender3 and to simply snap into place onto the cover of the X axis pulley.
The camera case works for the standart size camera (~24*25mm with 4 mounting holes 20mm appart in width and 12mm in height)
Quite easy to print, the supports should be easily removable. You can add a brim if you are concerned that the arm might warp.
