It's chassis, built from lasercutted 3mm Steel, gives her great strength, simplifies the build process and eliminates the need of several printed parts due to the use of steel plates instead of threaded rods for the "y" subframe.
Now you can buy bolts and nuts too. (40 bolts M3x12mm y 40 nuts M3)
Improvements over the standard Prusa i3
Stronger frame due to it's construction on structural steel.
Solves the frame oscillation thanks to its reinforcement squares.
Simplifies the construction, eliminating the complex subframe of threaded rods in the Y-axis.
Once assembled, everything is its place, no adjustments needed.
Eliminates the need of several printed parts.
The steel mounts for motors and rods, are infinitely stronger than their plastic counterparts.
The only two threaded rods needed are the ones for the Z-axis.
Uses shorter smooth rods lowering the build costs.
Once assembled, it forms a solid structural unit that can be transported as a block.
