Contertop challenge entry #CountertopChallenge
This is a box with ventilation to keep garlic or other food that needs airing to prevent moisture ruining it.
By printing with 22-25 filling and 0 mm top and base thickness, the cover and the sides of the box are printed as grills, so air can circulate. I developed this trick initially for electronic boxes, which also need ventilation. The letters and 3D garlic pieces add a nice touch to the attractive grill effect. You can experiment with the filling % for different grill effects.

I love 3D printing!

I insist, the trick in printing this with grill sides and top is to print the box vertically and the cover flat, both with infill 22-25% (I use Cura for slicing), and 0 mm bottom and top thickness, plus a 2-4mm shell side wall.
Otherwise, I changed the filament colour when the printing reached the upper surface of the cover. The trick for changing filaments without problem is to elevate immediatly the extruder (so the heat does not ruin the area nea where it stopped), by inserting something to support the bridge. Then I free the motors, and change the filament. You feed manually a bit (until the colour changes) of filament, and when it is ready, you push X and Y reset to zero, then "resume" button to resume printing with the new colour.
