Our take on the Graviton Funssor BLV Cube 3D Printer Aluminum Dual Z Axis Hiwin SFU1204 Ball Screw Z Mount Upgrade Kit Z MGN12H

This is a Z-axis upgrade kit for the BLV Cube FDM printer. It replaces the stock Z motion with SFU1204 ball screws and MGN12H linear rails, both Hiwin parts, mounted on silver-anodized aluminum blocks. The kit suits BLV Cube owners chasing stiffer, smoother Z motion and less layer inconsistency; it is a parts kit, not a printer, and needs the BLV Cube frame plus your own motors and tools. Against generic lead-screw kits it offers ball-screw efficiency and rail guidance, but it is a niche upgrade with no electronics or instructions included.

Questions and answers

What does this kit replace on the BLV Cube?
It replaces the stock Z axis with SFU1204 ball screws and MGN12H linear rails on aluminum mounts. The rest of the printer, including motors and electronics, stays as is.
Are the rails and ball screws genuine Hiwin?
The listing names Hiwin SFU1204 ball screws and Hiwin MGN12H rails. Check the markings on the parts when they arrive, since copies circulate.
Do I need new motors for the ball screws?
No motors are included. Ball screws are efficient, so the stock Z motors usually cope, but you must set steps and Z-offset in firmware after fitting.
What hardware is in the box?
The screw pack has 22 M3x8mm, 12 M4x12mm, 14 M5x8mm and 4 M5x40mm screws plus 10 M5 T-nuts. The aluminum mounts and rails are the main parts.
Does it fit other printers?
It is made for the BLV Cube. Mounting holes and rail lengths are sized to that frame, so fitting it to another printer means drilling and custom brackets.
How do I maintain the ball screws?
Keep them lightly greased and shield them from dust and filament debris. Dry or gritty ball screws add friction and can show in Z artifacts.
