OPENBEAM Mitre Box

OPENBEAM is an amazing new aluminum extrusion design that gets rid of the expensive T-nuts used on other extrusions types.

It replaces the expensive T-Nuts with M3 sized nuts and bolts that are available form most hardware stores at an fraction of the T-Nut's cost.

To cut the extrusions a bit easier and more accurate I designed this Mitre Box.

It has a slot for 90 and 45 degree cuts.
