Corner connector to join Makerslide with 20x20mm extrusion.In the process of expanding the worksurface of my ShapeOko, I needed a bracket to join the Makerslide to 20x20mm extrusion. There are 4 pieces needed: 2 right brackets and 2 left brackets Assemble as shown in the photos, mounting the baseplate to the Makerslide first. It is set up for M5 x 10mm machine screws; it works but it's a little tight with the socket head screws. Button head screws will give a little more working room, but the socket screws work fine, if a bit fiddly. Use of sandpaper and shims may be required for best alignment. These should also work with 20x60 and larger extrusions.
