I too have a Prusa i3 and I would like to use this quick fit carriage. I would need the X ends and I tried the above link and tried searching on Jonaskuehling and could not find the files. Could you direct me to the files that will work with a Prusa and your project. Thank!
Great Design - Very Rigid due to it's Box Style Construction + 4 Corner Mounted LM8UU Bearings - Extruder's fit very tightly & give good results when printing - Chucked our old X-carriage in some acetone to make ABS glue and converting other machines to use this the Richrap X carriage - Had no Issues at all Sliced well in skeinforge & Printed out fine in grey ABS . the only changes made was i added a little extra material on the fan end extruder clamp as i plan to be swapping a lot of extruders & wanted to be 100% sure it was strong enough for 100's of Swaps - THANKS Richard great design.

The Linear bearings slide in and secure with a zip tie
It has a belt adjuster on one side of the belt clamps - see photos
The Extruder is based on Greg's excellent design, with a few mods and the extensions allow it to fit on the Quick-Fit X Carriage.
You need two x M4 (13mm) 624 bearings for the Quick-Fit Lever.
It also has a fan mount on one side.
It's designed to be expandable (easily made wider) by adding spacers between the two halves - without taking off the printer. - just in-case you ever need more room to fit triple extruders !
