I bought a cubify cube off ebay that did not have a Print plate for it so I designed this printed it and tested it with PETG and worked EXCELLENT . Shipped it off to get it milled from 3mm alum plate and was very much impressed with this it uses the default hardware from the magnetic mount.

The bed Leveling is done with a 4.5mm melamine sheet cut to 6x6" with holes drilled on the outer edge to match with the heated bed I got from printrbot 6x6 (which works WONDERFULLY for this application). A few springs and some nuts and bolts for the leveling system and plop a piece of glass from the local shop on the bed as a print surface makes for a GREAT setup. Glass is 5x6" 3/8" thick.

the STL Can be printed and used as is and is very solid when done in PETG with 50% infill

this was primarily made to test and then put into production to be milled and should only be used to test till you get you milled out
