Print two lefts, two rights, and four supports. Zip tie the corners to the crate and mound the supports to your machine. The machine should now sit well on top of a milk crate. I have mine tied on for improved stability and ease of transportation.

I have included two types of supports. One is intended to be attached to your machine by the bottom rod that goes through the foot. The other is simply a spacer that fits around the foot and between my power mount and the corner.

I made some bottom vertexes with a protrusion that eliminates the need for the spacers.
