I'm using

2x MGN9 linear rail (length 300 mm)

To be sure that the mounting plate fits on your carriage block, I added the dimensions of my MGN9H carriage block. Please compare the thread positions.

Assembly instruction

1. screw the carriage block and the mount_single with M3 bolts together.
2. screw the 2x linear rails to each side of the y-axis printer T-nut profile. To ensure that the linear rail does not tilt, use the support_plate_rail between the linear rail and theT-nut profile. Therefor you need M3 bolts and T-slot nuts.
3. put the carriage blocks on the linear rails, one block on each side.
4. assemble the Ender 3 bed to the mount_single with M5 bolts. You can use the stock bolts from the original roll guide. Be sure that the carriage blocks slides easily along the rails. if this is not the case, you can try to align the linear rails horizontally and adjust the mountings on the carriage blocks.
5. assemble the belt at the ender 3 bed
6. To ensure that the carriage block is hitting the stock y-axis endstop, you can use the stop_extansion by placing it on the endstop.
