About this 3D model

If you are building with Open Beam you will need one of these. Has 45 degrees as well as 30 and 60 and is gapped for a standard hacksaw blade. I recomment holding this in your hand on a solid work bench and taking your time with the cut. Use a 24 tooth hacksaw blade for a neat cut. Open beam is a 15mm x 15mm aluminium extrusion that I am currently building with.
