Da Vinci Logitech C160 Webcam Mount (Octoprint Video for under $7)
a remixed a generic webcam mount into one specifically for the Logitech C160. The C160 was the cheapest Octoprint officially supported USB webcam I could find.
The issue though? it was too big to fix in the space.
The solution? Break off the plastic case of the webcam and mount the board and lens in a simple printable holder.
