YubiKey 5C NFC (USB-C) Key Ring Case

I uploaded an updated version here: https://makerworld.com/de/models/2339177

The new design increasing the usable hole diameter for the key ring — standard key rings fit more easily. And a new variant for the YubiKey 5 (USB-A) has been added.

YubiKey 5C NFC (USB-C) Key Ring Case

Overview:
This is a remix of @Mige’s excellent “YubiKey 5C NFC key ring”.

What’s New in This Remix:

• Added side wall so the YubiKey can only slide out in one direction
• Additional notch for improved grip and easier pulling
• Flat base to allow clean upright printing
• Two versions included:
  • “YubiKey 5C Key Ring Case Offset” — notches offset
  • “YubiKey 5C Key Ring Case Aligned” — notches aligned on the same level

Printing Recommendations:

• Orientation: Print upright (as shown in the last image)
• Supports: Not required
• Material: PLA or PETG

Design Notes:
The hole for the keyring is quite small by design. Standard keyrings won't fit, you have to use a small one.
