I don't like the chip basket style enclosures for the Anycubic wash and cure, so made a platform instead.

Uses modifier parts to get the hexagon pattern, but change it to grid or whatever you'd like easily. No air pockets so it doesn't float about, and fits snuggly against the walls, just have to push it into final place.

I made mine in PETG and it works fine, PLA should work too.
