3D printed Minimalist Wallet

Version 1

Version 1 was our first try. We experimented with a screw design which ended up with several quirks:

Limited Space: Not enough room for coins.
Design Constraints: The width was dictated by the minimal screw length.
Rubber Band Mechanism: A rubber band was clamped in and wrapped around the wallet, aiming to secure money bills.

This early version was a stepping stone towards a better design. Future iterations will focus on expanding storage and refining the fastening method.

Version 2 introduces a refined design approach:

Integrated Rubber Band: The rubber band is now sewed into an endless loop, hidden within the wallet.
Custom Covers: It features custom designed, exchangeable covers that are press-fit. They’re typically glued on for long-term durability.
Enhanced Coin Compartment: The coin compartment is significantly larger and better designed, featuring a click-in-place hinge for secure closure.

This update gives the wallet a sleek, multicolor finish right from the first layer:

Swappable Filaments: The cover shells allow for filament swaps, making a multicolor print possible.
Clean Design: No extra edges, bridges, or structure—just pure color.
Flexible Options: If you prefer a more structured look over the color effect, simply omit the colored objects and print the shells as they are.

Software Setup:
- Use PrusaSlicer. It supports 3MF files and lets you hide parts of your model.
Slicing Process:
- Load your 3MF file.
- Hide the shells and slice only the color infill.
- Then, hide the color infill and slice only the shell.
Printing Steps:
- Print the color infill.
- Swap the filament.
- Print the shell.
Tips:
- Skip the brim or skirt to avoid interference.
- Keep an eye on the print bed temperature—add custom G-code if needed to prevent it from cooling too much.
- With an 11-minute print, manual intervention works just fine.
