My opinion is that the entire top X section need re-thinking because the ends bend in like a crossbow when the belt is pulled together. It is just a slight bowing at first but gets worse over time. Really there should be two paralell beams rather than just one Or redesign it so the smooth rods cover the entire distance of the beam to double as re-enforcement to stop it bowing. After such a mod then yes, perhaps.Â The printrbot is a very promising simple design that I think should get lots of attention. My hat off to Brook for inspiring me to build and modify my first bot!

Of course you will need the original PB Extruder Mount which is included here in the files for your convenience.
The new X Beam just has the endstop holes moved so just drill the new holes carefully if you cant source a new laser cut part. The new X Carriage part has a small notch for hitting the newly placed endstop which must coincide with eachother obviously.
The new black front securing plates shown in the pic are just so I can use M3.5x37 countersunk bolts in my design and are not essential to this mod.
