Ultimate Ender 3 Webcam Mount

This is a small arm that uses existing screws in the Ender 3 frame to attach to the printer. It is ideal for webcams because it has a flat arm on which the webcam can sit, pointed directly at the center of the print bed. It's designed for a Logitech C720 but it should work with virtually everything else, and includes some mounting holes for anything that doesn't. It has a triangular skeletonized design to make it cheaper and more stylish.

The “Behind” version has the camera sit next to the extruder, while the “Front” version has it in front of the printer. Depending on how much space you have or which camera angle you want, you can choose which one to print. FreeCAD (Ondsel) files are provided to let you customize it further.
