Model originally uploaded to Thingiverse at https://www.thingiverse.com/thing:2930445.
I remixed the original so as to lower the camera. It now points more towards the nozzle. The bracket moves less and still has the features I liked from the original design. It will pop off easily and it required no modification to the printer itself. The only downside of the design is that since it follows the z-axis, you really only see the object as it is printed. It is pretty much out of sight when it is finished. This is fine for me since I really want the webcam to check progress.
I printed it in PETG with no supports.
Update: I printed this https://www.thingiverse.com/thing:2446030 to make it easier to focus the webcam. I used #4 x 3/8" wood screws I had around.
I added 2 new .stl files
- lowers the camera even more
- moves camera out 2 different distances to clear the printhead. The more extended version shows more of the build plate and makes focus a bit easier but required more space
- changes the angle to point more at the print head..
- the final image is from the latest, longest arm ( C270_Mount_for_Original_Prusa_i3_3_1a.stl)
