Khối Y E3NG Beta cho V1.2

I adapted the original beta NG Y gantry blocks to fit on the NG 1.2
They are considerably heavier, but also considerably stronger.

I included a shorter and an even shorter endstop switch mount.
The shorter one should suffice in most cases.
However with Klicky probes you may want the even shorter version for that extra bit of reach on Y (difference is only 1.5mm but it helps)

BOM
 

• 4x M5x50mm SHCS Bolts (can be button head too)
• 8x M3x16mm SHCS Bolts (can be button head too)
• 4x M5x6x7 heat set insert (or similar)
• 8x M3x4x6 Heat set inserts (or similar)

Other components are identical to the original NG, so same bearings, same spacers.
