The origin of the Compct. project was to create a gift for family, practicing my skill in CAD-modeling and utilizing 3D-printers.

I was inspired to create a wallet, as other members of Het Beun Collectief were at the time individually creating different wallets after a running joke. It was a, “hold my beer, ill show you something better” situation, pushing me to create something more elegant, compact and sustainable.

Inspiration was quickly found in the simplicity of the ridge wallet, which was compact and minimalistic. I modelled a standard credit card, and set the requirement that the wallet should refrain from being any broader than the footprint of this card. The final design indeed housed this compact and minimalistic structure, consisting of two interlocking halves held together by an elastic band.

Individual project

For this project, I independently managed the full design cycle, from concept to final assembly. Since I was the only stakeholder, I utilized this opportunity to gain experience and strengthen my skills in CAD modeling, prototyping, and precision manufacturing.

Functionality Realized

Small Footprint. Easily fits into pockets due to footprint of a regular credit card.
Simple Interaction. By forming indentations (top-right and left-bottom) cards can be easily pushed out of the wallet.
Separation. The wallet can hold both cards as paper bills secured in separate locations.
Flexible. Up to 10 cards can be held comfortably
Sustainable. Modular assembly (5 replaceable components, 4 fully recyclable) allowing for repairs and part replacements

Skills Used

Tools & Software

Onshape, CNC Machining
& 3D-printing

Technical skills

CAD-modeling, Material Selection & Prototyping

Design principles

Sustainability & Modularity

Features Realised

Small footprint. Due to the model consisting out of two halves, connected by elastic band
Weighted. Use of brass sheets adds weight to the wallet, increasing the feel of structure.
Personalized. CNC-engravings
Sturdy. Including a printed bumper around metal
Industrial look. Through use of binding phillips head screws

Compct. is currently being tested throughout daily life by multiple individuals.

After experiencing real-world use for a year, I intend to further develop Compct.02 to further solidify the design for sustainability and durability.
