Multi-function Card




Introduction: Multi-function Card

I have always needed a handy tool. Since I use different tools on a daily basis, I created the Multi-function card. If fits perfectly in your wallet and it fits in your pocket. It is made from durable plastic and is sure not to break. It consists of a small wrench, a centimeter ruler, a can opener, a bottle opener, a flat screwdriver, and an envelope opener.

Since I heard that there would be a pocket-sized contest this year, I thought this would be an amazing thing to design out and make. In the end, it worked out very well, and was very durable.

I hope you will try to make this project!!!

Step 1: Materials

You will need:

- A 3D printer

- Any type of filament (preferably ABS)

- A sander or sandpaper

Step 2: Drawing It Out/ Designing It on Paper

These were my first initial designs on paper.

Step 3: Designing and Printing the Card

I used Fusion 360 to design it.

I printed it out with 100% infill because it would lead to the card being stronger.

Step 4: Sanding and Final Touches

I sanded the envelope opener because I wanted it to be sharp. (Don't make it too sharp though, otherwise it can cut you when you take it out of your pocket or wallet.)

Step 5: Testing Out the Functions

All of the functions of the card worked very well. The ruler was exact, the bottle opener worked well, and the mail opener cut very well.
