Stainless steel frame for Prusa i3 Steel (P3STEEL)

Improvements over the standard Prusa i3

• Stronger frame due to the use of structural steel.
• Solves the frame flexing thanks to its reinforcement squares.
• Simplifies the construction, eliminating the complex subframe of threaded rods in the Y-axis.
• Once assembled, everything is in place. No adjustments needed.
• Less printed parts.
• The steel mounts for motors and rods are much stronger than their plastic counterparts.
• Only two threaded rods needed are the ones for the Z-axis (5mm).
• Uses shorter smooth rods lowering the build costs.
• Solid structural unit that can be transported as a block.
• The interference between the Y stepper and the M3 nyloc nut holding the Y stepper support has been solved by stretching the support by 2mm.
• Filament spool holder made in steel S235JR
