Hey there! - Just yesterday I 3D printed a mount for placing a Microsoft VX webcam onto an ER1 robot. A fellow robotics enthusiast suggested I upgrade the webcam on the ER1 and I used the upgrade as an excuse to learn 3D CAD modeling and design. A before and after video can be seen on my FB page dated 1/5/2016. the FB page is at:
