I have updated the design, I have added a spacer object. Also instead of having the Y-axis bars under the frame bars, I have put them on them.
I think it has a really low friction as I tried to demonstrate in the vid: [

My only concern is that the bearrings have some room to move inside the bearing housings. But that might be easily fixable with some toiletpaper or something.
