HyperCube Z with support 16mm rails

Still waiting for rail and bearings to be delivered. This was done to support a 300mmx300mm bed. Still needs to be tested. Rails are 500mm and screw is 600mm. If there is no play may consider replacing screw with ball screw. Vertical 2020 needs 3mm holes to be drilled so 5mm hex head screw slide in the back of 2020 and screw in the bearings. Once finished I will publish template to drill holes correctly.
