I'm playing with mounting the linear rails in this fashion for my next printer, it works out ok then?

Seems fine definitely a bit of improvement in print quality. The only tricky thing as I said on the write up is getting the width correct between the two y axis rails if you can come up with an adjustable mounting between the x rail and y slides that would be solved. I ended up bonding it then power sanding the y slide where they meet the y rails to fit.

So I have added two revised motor mounts to the listing above for the linear rail conversion. They have a few features that were relevant to smooth rods removed, and have the motors positioned 1.5mm towards the centre of the printer to correct the belt geometry to pretty damn straight between the y-slides and motors. It is assumed you are using 608zz bearings or other bearing of the same diameter, and 16 tooth pulleys to get the correct geometry. Please attach the motors with plain hex head m3 bolts (not allen key cap headed screws) and do this BEFORE you attach the mounts to the printer or you will be driven mad by how fiddly it is.
