SnapLock Card Boxes – Toploader & Sleeved Cards (Remix)

Remix of "SnapLock Storage Boxes" by Hugo – all credit for the brilliant snap hinge and clip system goes to him.

I kept his hinge, latch and clip geometry 100 % unchanged and only resized the boxes for trading cards standing upright.

Your existing SnapLock clips fit.

TOPLOADER BOXES

(standard 3"x4" toploaders, up to 77 x 103.2 mm)

- S: holds at least 25 toploaders (approx. 26–31, depending on brand)

- M: holds at least 50 (approx. 57–69)

- L: holds at least 100 (approx. 100–120)

Inner width 78 mm.

Toploaders stick out 5–7 mm above the rim, so you can grab them, and still clear the closed lid.

SLEEVE BOXES

(standard sleeves, up to 67 x 93 mm, single or double sleeved)

- S: 1 deck + spares (approx. 92 single / 72 double sleeved)

- M: 2 decks (approx. 196 / 154)

- L: 4 decks (approx. 340 / 267) Inner width 70 mm. OPTIONAL EXTRAS

- Divider card with center tab to separate decks (fits under the lid)

- Card support wedge to keep a half-full box from leaning

WHAT I CHANGED

- Widened and deepened the boxes for upright cards; L is lengthened to 196 mm inside

- Filled the inner bottom chamfer to a flat floor, so the card corners don't tip

- Tuned the height so cards are easy to grab but don't touch the lid

- Hinges, latches and clips: unchanged from the original PRINTING

- PETG recommended, 2 walls, 15 % infill (same as the original)

- All parts are already oriented for printing

- Clips: 1 for size S, 2 for M and L (the original clip; included in the 3MF files)

- Each 3MF contains one complete box on one plate (tested on a Bambu Lab X1C) NOTES

- Capacities depend on toploader and sleeve thickness, which varies between brands

- At the very ends of the box, the outermost cards may lightly touch the lid's inner corner
