Prusa i2 Rod Kit

This is a complete set of threaded and smooth rods for a Prusa i2 printer.  All threaded rods for the frame and z-screws, and smooth rods for all axes are supplied in the following specifications and quantities per the iteration 2 wiki at http://reprap.org/wiki/Prusa_Mendel_(iteration_2)


  • 6 370mm M8 threaded steel rods
  • 4 294mm M8 threaded steel rods
  • 3 440mm M8 threaded steel rods
  • 2 210mm M8 threaded stainless steel rods
  • 2 350mm 8mm smooth rods
  • 2 405mm 8mm smooth rods
  • 2 420mm 8mm smooth rods
  • 1 20mm 8mm smooth rod (for Wade's Extruder)


Z-screws are cut from high-strength stainless steel.  All smooth rods are cut from high-strength, precision ground annealed O1 tool steel.  In order to keep prices low, all threaded rods for the frame are cut from plain steel.

* Diameter tolerance for smooth rods is +/-0.013mm
* Thread fit for all threaded rods is 6g
* Length tolerance for all rods is +/- 1mm


NOTE: The 20mm rod for the Wade's extruder is supplied as a smooth rod (O1 tool steel) instead of the threaded rod that's indicated in the wiki.  This smooth rod has much tighter tolerances for supporting the idler bearing than threaded rod does.  If you wish for us to include a threaded rod for this instead please send a message after creating your order.
