I was unable to source a regular y-carriage for a reasonable price for my Prusa i3 so I designed a y-carriage which can be printed on a 200x200 printbed. Can use three or four LM8UU bearings.

Designed to use i3 alu bearing holder designed by richard_j_m which is available on Thingiverse:

I also made larger arms so it can be used with a 300x200mm heated bed as I am using now.

Materials and methods

-3 or 4 LM8UU
-8x m3x30 screws for assembling the parts
-4x m3x20 screws for mounting the belt.
-2x tie wrap per bearing

To be printed:
-4x smallarms (or 2x large arms for 300mm)
-2x belt latch
-1x carriage
-Bearing holders for each bearing
