In the Machine Design assignment, we organized ourselves in a collaborative way to work toghether and individually in different tasks. In my particular case I worked closely with Arch. Rafael Garza in the complete assembly of the mechanical components for the different axis. For the stepper motors and guide enclosures we used 4mm thick structural cardboard.
Since it´s probably thicker than the regular and Science cardboard, we had to remake our first assembly from scratch and modify the further enclosures so the effector box can run freely on the guides without touching the enclosure walls, which ment a lot of new cuts.
I´ve also welded the components on the FabNet board.
First iteration, bigger cardboard thickness not considered resulted in a Bad Robot!

At the end, it was decided that this would be a good opportunity to have our own 3D scanner, so we went on that direction. (as shown in the assignment link.) On that particular, I´ve designed a tiltable iphone cradle that can be oriented angularly in a 45° sweep around a point of interest.
This cradle was designed in Rhino to be laser cut in 6mm thick acrylic:
