The DUMB Wallet w/ Keychain Ring (Simple Card Wallet)

Sleek, Secure & Satisfying Design

The wallet secures your cards with a tiny notch at the top so it doesn't matter how many there are. Enjoy a satisfying click when are card is fully secured. The rounded edges also make the wallet comfortable to hold.

This mechanism is from the original model: The DUMB Wallet by npopson.

Hang AirTags, Trinkets and more off of your wallet…

Use the wallet made by npopson but with holes for your keychain. This allows for the addition of location tracking (via AirTags) or personalisation though any printed trinket of your liking.

• Adds keychain holes while maintaining the simple appearance of the original model.
• Functions exactly the same – so you know it will work.

Keychain Ideas

Here's a few keychain ideas below with some examples of models I've seen on Printables.

• AirTag - keep track of your wallet's location
  • AirTag Holder by TC.
• Tiny 3D models - extra personalisation
  • Tiny 3D Printer by Jan Štech.
  • Spool Keychain by AK3D.
• Name/contact details - if you lose your wallet
• USB stick - always have storage on you

Print Details

• No supports.
• Works in any material.
• Brim is optional – use if you need more adhesion.
  • If using a brim: Make sure to clean up the bottom of the model completely for a smooth finish. The bottom should contain no sharp edges. See an image of a fully removed brim below.

• Loads of sizes (let me know if your really need a 9+ card version):
  • 3-card
  • 4-card
  • 5-card
  • 6-card (used in the images)
  • 7-card
  • 8-card
• Planning for the future is fine – using 3 cards in a 6-card model will still have a secure fit. Note: if you would also like to store cash, go about 1-2 sizes above your number of cards.

This model is a remix of npopson's wallet with a redesigned bottom to allow for the attachment of a keychain on either side without any compromise on looks and function.

Compared to the original model:

• Identical design for securing cards in the wallet.
  • Clicks when the cards is secure.
  • Doesn't matter how many cards are in the wallet, it will still be secure.
  • Comfortable to hold.
• Adds a ≈3×3 mm diagonal hole on each of the bottom corners of the wallet.
  • Note: the 7 and 8 card .stl models contain a ≈4×3 mm hole allowing for slightly wider material to be thread through.
  • Model is around ≈5mm longer.
• Using V1.1 of the original model's design.
