This is a different style parametric bed bracket. Both mounting screws face forward and it has a key that first in the top of the extrusion. This makes it easier to install. You can slide them in, attach the bed and then center the bed and tighten them down. They have adjustment slots for the bed screws so there is some wiggle room to get the exact fit. Because they are flush with the bottom of the extrusion, you can use oversized adjustment wheels.

Printed as is, they will fit the standard hevo with the MK2A (328mmx328mm) bed.

Note you will need M3 screws of 40-45mm.
