Leadnut for printed linear bearing and 20mm y axis

thingiverse

I've been tooling around with a bunch of scrap from other cnc / printer / laser projects looking for a way to increase the size of my printer drastically. I have a frame mostly finished of 1" 80/20 with aluminum angles and brackets all around giving around 13 inch travel in x and y, z.. I had enough openrail and 20mm extrusion for the X and Y but not Z (and i figured this to be the most susceptible to wobble), so I wanted to try the printed linear bearings for the 1" 8020 which i had extra of (http://www.thingiverse.com/thing:82248). These bearings had an endcap for 1" 80/20, but I was planning on using 20mm extrusion and some leftover openbuilds parts for my x axis. Additionally, I had selected this motor mount (http://www.thingiverse.com/thing:390669) The thing I have created (the white part in the photo), connects the linear bearings to the 20mm x axis and puts the "leadscrew" (5/16 threaded rod right now) in line with the motor mount. It screws onto the linear bearing with 4 M3 screws like the original endcap did.
