Y carriage for RepRap

I use this carriage on RepRap Prusa Mendel i2.
ABS. 0.25mm layer height, 25% Infill
This model made in SketchUp Pro 2015 v.15.0.9350

Features of the Y carriage:
- easy to print
- easy to install
- compact and looks good (IMHO)

Except this model you need to print some other models:
