MakerSlide or 20mm extrusion parallel joiner
thingiverse
Joiner to connect 2 MakerSlide rails together. I designed these to allow me to double up the X rails on my ShapeOko CNC machine. In addition to the MakerSlide rails, these should also be compatible with 20mm extrusions from Misumi, Maytec, Alufab, Bosch Rexroth, Easy Systems, and 80/20 Inc. Instructions Printed at .25 mm layer height using whpthomas' 200 micron profile (http://www.thingiverse.com/thing:39050). To assemble you will need to hammer the joiners into the extrusions. It is normal for a bit of plastic to scrape off as they go together. I designed them to be a very tight fit to insure the rails are pulled together. If working on longer spans, I would recommend using a rod to drive the connectors to the middle of the span (print 2 sets).
