The final revision is now uploaded, all of the tolerances should be perfect for properly configured printrbots.
9/24/12 - X-stop is fixed in place, non-adjustable
10/04/12 - Motor mount now compatible with 28mm 36 Tooth GT2 Pulley
10/09/12 - Added LME12UU compatible parts. (See notes)
03/01/13 - Replaced by V2.0 http://www.thingiverse.com/thing:55845
If the alignment of the Z-stop is off, heat the arm of the motor mount with a torch/lighter/heat gun, then bend and hold the arm to its proper alignment until cooled.
Tolerances for the length of the LME12UU bearings are very close. Fitting the bearings may require additional finishing. One way of setting the bearings is to soften the plastic with a torch/lighter/heat gun before pressing the bearings into place.
