Pokémon Card Case - Poké Ball Style with Snap-Fit Lid

My son asked for a case to hold his cards, after I asked him to stop leaving his cards all over the place. Fair deal. The lid features a red and white face, black band, and white center circle, with shallow V-grooves between the colors. Filament switches are necessary, but kept to a minimum. You can print it single-color and still see the shape from the V-grooves. Internal space: 65mm x 90mm x 18mm, enough for around 50 cards. If you own a Bambu printer and current software, you should be able to open the 3MF and match the colors automatically. For other printers, import the lid 3MF as one object with multiple parts. Do not split or arrange the colored pieces separately. The base and plain lid STLs can be printed without a multicolor system. The plain lid has no color divisions or decorative grooves. I printed the one in the picture with Bambu PETG HF, a 0.4 mm nozzle, and 0.2 mm layer height. The top and bottom layer counts are intentional. Together, they cover the 1.8 mm floors at 0.20 mm layer height. This avoids printing a sparse-infill layer followed by the bridge layer over it, which adds printing time. The lid should snap into place easily, but not fall back off easily. Mine fit great, but different printers and different settings may yield different results.
