This is basically a Prusa i3 Einstein Rework with minor changes such as:

• wood-style frame with fins
• stronger x-end-idler

Instead of the original threaded rod configuration, you need

• 2x Threaded rod M5x300 mm
• 2x Threaded rod M10x210 mm
• 2x Threaded rod M10x365 mm
• 2x Threaded rod M10x380 mm

and a few more M10 nuts and washers plus two M8 x 20 mm screws.

You also need to tap the printed X-END-IDLER-BETTER.stl twice with a M8 x 1,25 thread. Thats where the two M8 x 20 mm screws go.

Besides that, just follow the instructions from the original project page

• modifying the x-end idler to more solid, right now the ball-bearing mount it's a predetermined breaking point
• modifying the wood frame fins to fit the i3 EINSTEIN Rework y-corners and 10mm threaded rods
• modifying the y-carrier for 3-point leveling AND for triggering the lower y-endstop even if the bed is mounted a few mm higher (i.e. due to leveling screws)
