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.


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).

Marvelous simpel.
I have printed these and tried them on my dual x-as.
This works even better then with screws and bolts, and you cannot even see them.

Thanks! ! ! !

I think I'm missing something, Why exactly do you need these?

These will connect two extrusions together as the description states. I used them to double up the rails on my modified Shapeoko CNC mill to reduce the spindle deflection. The printed parts align and hold the rails together while I reassembled the machine.

I've just been calling around to see if anyone makes hardware like this! Thanks.
