Rectangular & cylindrical box lids are telescoping (slip over the outside) with an adjustable slip-fit gap — start at 0.2 mm and loosen if it's tight or tighten if it's loose. Matchstick & seasoning containers screw together on a right-hand thread that auto-scales to the diameter; the lid screws onto a recessed neck so it finishes flush with the ribbed body (same outer diameter). The lid threads are cut as a tapped groove into a solid wall (no unsupported teeth), so they print clean and tighten securely; tune the thread fit clearance if the lid binds or is loose — 0.25 mm suits most printers, and you only need to re-print the lid to dial it in. Two-tone text — on keychains & tags, leave text raised and pause your print at the layer shown to swap filament, or choose Recessed and set the recess depth — from a 0.10 mm shadow up to a cut clean through the plate — so a multicolour printer / slicer can paint it a second colour. Lid text — choose Raised or Recessed and set its depth/height; recessed pairs with a multicolour slicer. Invert lid flips the lid in the preview into its print orientation (threaded / skirt end up, decorative face down) and forces a shallow 0.10 mm deboss on the text — because that's so shallow, you'll need to paint the text a second colour in your slicer to see it. Printing — keychains, tags and boxes all print flat-side-down with no supports; print lids open-side-up. For watertight boxes and containers use 3+ perimeters and 4+ top/bottom layers. Pair with the Calibration Print Generator to dial in your printer first. Right-click any slider to type an exact numeric value.
