Printer mods?

Is there a set of files to be able to mod the new printer design?

Specifically I am looking to be able to use half inch rod and bushings. I have a good amount of straight half inch stainless rod in stock here and several hundred self lubricated bushings for it.

Since the bushings are smaller OD than the bearings, it seems that there would not be much to mod aside from the rod holders and bearing holders?
