ELP 720p USB Webcam module enclosure and mount

thingiverse

In search of perfect Webcam to use with my 3D printer (via Octoprint) (Logitech C270 is good but it has very narrow field of view) I discovered these awesome [ELP USB camera modules](http://amzn.to/2y4V81C). They are small, cheap, have wide lens and work great with Raspberry Pi. This is complete enclosure and mount "stem" that can be attached to 2020 extrusion frames like one on Creality CR-10. There's also a mount for MakerGear M2 printer. M2 mount is simply attached to frame corner and uses M3 nut and M3 screw to hold it securely in place. IMPORTANT NOTE About ELP camera and OctoPi image: I've discovered that if you are running Octopi (Raspberry Pi image with Octoprint), it will not work with ELP cameras by default. This is due to Octopi distro trying to start camera with 10 frames per second parameter. It looks like ELP cameras do not support that. Fortunately this is easy to fix. - Edit /boot/octopi.txt file - Find line (it will have hash/pound sign in front of it: camera_usb_options="-r 640x480 -f 10" Remove has/pound sign (uncomment) and change -f value from 10 to 15, like so: camera_usb_options="-r 640x480 -f 15" - Reboot
