Parts:

2x m3x6mm

2x M3 hexagonal nuts

1x No.11 surgical knife

Changes from Rev1 to Rev2:

Divide the knife holder into two parts and clamp the blade in it.

The size of KnifeBottom has been changed to reduce the possible gap on the wall.

+ Other minor adjustments

If possible, use a 0.2mm nozzle in combination with the Arachne wall slicer.

The screws at the back can be tightened as needed; the tightness of the screws near the blade controls the difficulty of pushing the blade out.

When using Rev2, you can easily replace the blade by unscrewing the screw near the blade. Then remove the blade component. Replace the blade and reassemble it.
