qu-bd oneup fixing for z axis

pinshape

I'm installing a screwless fixing on my z axis, which greatly reduces the wooble. Here are the instructions: remove the top left screw from your oneup. Next, install part three, followed by part one, then reattach the removed screw. Finally, attach part two. I've included an animated GIF for reference. After printing the parts, I had to clean the edges with a knife and use a drilling machine with 8mm and 10mm bits to enlarge the holes. The design still needs some optimizing.
