Description
This is an ultra-slim, fully 3D printable wallet, inspired by some of the best designs out there — especially the great work by MAXX and others.
The main goal was simple:
👉 Make it slimmer, more practical, and completely hardware-free.
By tightening tolerances in the cash compartment and slightly increasing the internal height (~+1 mm), this version can now fit coins as well, without significantly increasing overall thickness.
On top of that, I’ve added:
8-card and 10-card versions
Fully 3D printed pins replacing M2 screws → no hardware needed
(Based on MAXX reference: 101.5 × 63.2 × 13 mm)
6 cards: 14 mm thick
8 cards: 16 mm thick
10 cards: 18 mm thick
All other dimensions remain compact and pocket-friendly.
✅ Fully 3D printable (no screws!)
💳 Holds 6, 8, or 10 cards
🪙 Now fits coins (optimized storage)
📏 Ultra-slim design
🔩 Optional: can still use screws if preferred
⚙ Tightened tolerances for better fit and feel
Material: PLA or PETG recommended
Supports: Not required
Print orientation: As provided
Use the included printed pins instead of M2 screws
Press-fit assembly — no tools required
Optional: use metal screws if preferred or a drop of superglue in each hole after pressing in the pins
Coin capacity depends on coin size
Tolerances are optimized — printer calibration matters
PETG recommended for durability
This design builds upon and improves ideas from:
MAXX – Slim 6-Card Wallet
chking – Modular Wallet
Mike – Pop-up Wallet
Huge thanks to all original designers 🙌
