Core-T Printed Wheels Spectra Driven

I am now ready to introduce the Core-T (previous name I had was used by another robot)! It uses coreXY kinematics and is spectra line driven, with all printed wheels on 608 bearings for linear motion. The frame is a standard 30 series 30 mm extrusion. My main design goal was to avoid using linear rods/bearings and aslo vslot, openbeam, and/or makerslide. Those are nice, but a complete v-wheel/bearing package is around $4 a piece. It's almost fully running, right now I just have the x and y axes running. Here's the youtube video: [www.youtube.com].

My thingverse page for it is here: [www.thingiverse.com]. Here's a couple pics:

How much play do the printed wheels have?

It's manageable for the x-y axis, but it's too much for the z-axis on 3060 extrusion. I'm working on making a ball bearing based linear bearing for 30 mm extrusions. I'm going to try and use zinc plated BBs that are available at a lot of stores. That way I'm staying true to minimal cost. Not sure how loud it will be but it's worth a go.
