Dyne's Wanhao Y-Carriage C920 Camera Mount & Adapter

Edit 2016-07-11: Added a new STL file for the latest version of the mount. It includes pads attached to the corners to help prevent ABS warping; just break them off before installing. The other changes are a 1.5 mm thicker stiffening ridge and a more gradual curve on the support block.

This is a webcam mounting bar for the print bed (Y axis) of the Wanhao Duplicator i3 and its cousins, plus an adapter that attaches the folding base of a Logitech C920 webcam -- or really any reasonably small camera with a 1/4" tripod mount -- to it.

Note: Due to the potential proximity between the camera and the print head, it may or may not be possible to use this if you have a front-mounted part cooling fan/duct installed, such as the stock fan or the diiicooler. You will have to measure the clearance carefully. I was already using thorped's wanhao fan duct (which is rear mounted) so this wasn't an issue for me.

This was inspired by dumbcomputers' Wanhao i3 Camera Bed Mount (http://www.thingiverse.com/thing:1422072). The adapter portion was originally intended to attach to the flat portion of that, but I ultimately designed my own version in an effort to shift the camera away from the printer's home position (more toward the center of the X axis and further out from the bed). The adapter STL is still compatible with dumbcomputers' mount, but note that doing this places the camera very close to the print head. They may come in contact every time the printer homes or prints anything along the front edge of the build area unless you manually rotate the camera out of the way as needed.

Since the (relatively heavy) camera sits at the end of a piece of plastic that behaves like a diving board anytime the bed changes direction or there are rapid X axis movements, there is a limit to the length that can be given to the mount to move the camera further away without pushing the vibration to unacceptable levels.

An example of a timelapse recorded using this mount; the model being printed was V2 of my Finial Tetra (http://www.thingiverse.com/thing:1640653)
