3D model description

This is a upgrade mod to eliminate the front and back y-frame plates along with the cheap idler bracket and wimpy y-motor bracket.
This mod gives you stronger y motor bracket and a better idler tension .
Also changes the belt path to be perfectly aligned and closer to the bed.
And the y motor now sits outside of the frame area making it easier to align your belt.

there are 2 mod versions to choose from.
1 - azza z brace version with both types of feet.
2 - SWD2 rear mounted z brace.
I only uploaded the parts i modded and created.
The rest of the parts for the z braces can be found here:
