A real quick and simple end piece for 3030 aluminum extrusion to protect your table or floor from getting scratched by the extrusion. This piece was made for the Hypercube Evolution 3D printer build, but could really be used with 3030 extrusion for anything.

This model can be used as a spacer when assembling the Hypercube Evolution. At the bottom of the frame, the crosspieces that connect to the vertical pieces should be 10mm from the bottom. This model 10mm from the outer top surface to the innter top surface that the end of the extrusion rests against. It's perfect for quick and rough measurement of the 10mm spacing.
