This is a replacement part for the Nicer Dicer Magic Cube.
Important: This is not the default grid, only applies when you buy the extension to have a full cutting area.
See my other design to get the usual grid replacement.
3D printed in PETG.
I should have rounded the corners a bit more (maybe 4 or 6 mm fillet is better). It currently fits but I think it's not perfect.
