Visualize and Compare Material Thicknesses – A Must-Have for Designers!
This set of 7 3D-printed cards is an essential tool for designers, makers, and anyone who works with different materials. Each card is the exact size of a standard credit card, making them super easy to carry around and use in any setting. The cards cover a range of thicknesses from ultra-thin to more substantial options:

0.4mm

1mm

2mm

3mm

4mm

5mm

0.76mm (exactly the same thickness as a credit card)

These cards are perfect for quickly visualizing and comparing how different materials feel and behave, without the need for complex measurements or tools. I personally use them for every project to help me make informed decisions about material choices, whether I’m designing for 3D printing, prototyping, or selecting plastics for products.

If you’re a designer or engineer who wants to take the guesswork out of material thickness, this set will become your go-to tool. The compact, credit card-sized design makes them easy to store, yet incredibly useful when you need them most.
