Switch cards storage case

Inspired by the "Nintendo Switch Game Card Palette Holder Card" of Kimsun.
 

My daughter needed some additional features:

• Keychain hole - to secure the case (and avoid losing it!)
• Three screws fixation system - to make the case sturdier
• View through indicators - to see empty spaces without opening
• Pop-up holes - to ease card extraction with weak fingers

I finally made a parametric model to address several storage configurations and needs.

The baseline I have printed is a 4-tray case with 4 card slots:

• With this one, use 3xM3x30 mm screws and 3xM3 nuts (standard countersunk flat head screw)
• Use the 4-tray spacer model

I also provide models for:

• Spacers for 3 to 6 trays
• Trays from 4 to 5 card slots
• For the screws, I suggest you take a longer one and cut it to length

If you want more configations, let me know in a comment.

Enjoy!
