This thing is for mounting a D-Link DCS-903L webcam on a MakerBot Replicator 2. It is is optimized to get a good total view of the build chamber. You can get a good impression when you watch its live output: http://www.web-n-apps.net/makerbotI printed it with the standard medium settings (2 sheiks, 10% infill). There is also a version with (quite large) helper disks, as I had some issues with the mount bending up from the build plate. To install the mount, just remove the top middle hex screw on your replicator's front and put it through the mount and tighten the screw again. Remove the webcam from its desktop stand (silver nut) and install it on the mount. I like to install it up side down. Don't forget to activate the upside down flag in the webcam's image settings.
