RichRap's 3DR Carriages modified for 8mm rod and GT2 belt drive

Carriages for RichRap's 3DR, modified by JEZZMUND for 8mm Rod (using LM8UU bearings) and then my by myself to fit GT2 belt instead of spectra fishing line.

I haven't assembled my 3DR yet, however, I've printed the carriages to confirm that GT2 belt fits.
