This kit allows the use of a rail for the Y-axis on a Prusa.


Print (2 of the clamps if you are doing individual prints, the last STL is a full set, the previous are individual parts)
You'll need 10 m3s 10 to 16mm ea (4 for the motor, two for each clamp and two for the belt tie down)
2 m3 nuts
m3 washers as you wish.
One m5 20mm+ and washers for the idler
two 605zz bearings for the idler.
A Rail with carriage store.trinitylabs.com/linear-rail-and-car-for-y-axis/

If you decide to go with 608zz bearings for your idler instead, you'll want to bore the idler mount hole out a bit either before or after printing.

Added a taller belt tie down - the shorter one should line up better, but the taller one may make it easier to get the belt past the m3 heads.
