# Fabrication
A motivation in the design for this machine was a desire to practice routing on the Zünd. After punturing through holes with the waterjet I put the parts on the Zünd and used the optical registration feature to allign them. I made several of the 1/4" Al parts on th Zünd. Below is an image showing the edge of parts cut on the Zünd (on bottom) and waterjet (on top).

And this is an angled view of that piece.
And this is an angled view of that piece which was routed with a 6mm end mill, then finished with a 2mm to get smaller internal radiuses. It was tapped afterwards.

The optical registration didn't proove accurate enough to re-allign parts after they'd been moved. I tried a few times and the second pass was visibly off. For rapidity of fabrication I ended up waterjetting about half of the peices, but the machine came together within the week.

# Action
I made this 3 ply cardboard box to ship it to Fab14 and was very happy with it's preformance. Carrying the machine around I dropped it a few times but all was well.

At Fab14 I wired it up. Configured the SmoothieBoard and started printing using Pronterface and Prusa slicer.
