Upgrade for Prusa I3 R2 by NicolaP, Italy RepRap http://forums.reprap.org/read.php?359,669423 Design Fusion360 It's possible not to use antiwobble, but if the trapezoidal bars are a little twisted like mine, it's advisable to install the antiwobble as shown in the photo; The TOP_Z and DOWN_Z use "688Z" bearings; for TOP you could be using KFL08 flanged bearings, but I recommend using the bearings as described above. With flexible couplers, everything works well, and there is no sign of wobble or other mechanical errors. To secure bolts of acme, use screws 3.5x10 for wood.
