Tissue Box Cover makes a decorative shell that slides over a cardboard tissue box — pick a cube or family-size preset, or enter your box's exact measurements, then choose an opening, punch a honeycomb or wave pattern through the walls, and add a monogram. Boxes vary a few millimeters between brands and bulge when full, so Fit Clearance defaults loose on purpose — about 2mm per side. Resist tightening it unless you only ever buy one brand. Pattern Spacing sets how dense the cutouts run; denser patterns show more of the box inside. The cover prints upside down — top face on the bed, opening edge up — completely support-free. The preview shows it upright, but the export orientation is already correct: print exactly what downloads.
