Squaring Tool Attachment for 1515 Aluminum Extrusion

thingiverse

My friend required a compact solution for squaring the rails on his RailCore 3D printer, so I created a 15mm x 15mm square that screws onto a 1515 Aluminum Extrusion.\r\n\r\nI produced two small guides that ride in the center slot and feature notches to accommodate a standard metric nut. The square remains securely fastened by a M3 screw.\r\n\r\nI am uploading an alternative version without guides for those with extrusions of different slot widths.
