I have built three cncs to date but never a laser, so being my first, I'm taking my time and using printed parts whenever possible as they cost me next to nothing. If they end up having some flex, just as easy to swap out with milled parts.
I couldn't agree more with Bart's comment about testing on the bearing. I wasted a lot of time printing beause I follishly didn't test the first one. None of the bearing related parts held them properly.
My printer works with PLA, which I've found to be a solid amterial for this application. In some cases, I've even re-designed parts to avoid hardware, like the z-table lift.

Files where originally in rhino but my trial expired on this one and before I got the new license, I swapped to sketchup with an STL exporter, which works fine for these simply geometries.

The part all the way on the right is 1/2 the redesigned z-table lift. It has a relief for a 1/4" nut and five holes - 2 for attached to the main frame, 2 for attaching to the table frame and one for the lead screw to go through and line up with the nut. Two of these [printed pieces are fitted around a 1/4" nut, making a complete z-table lift assembly.
