About: I love creating and making things. I make a 3D printer and I usually print parts to improve the machines that surround me, things to help my daily life and the people who ask me for help. DIY projects make m...

Nowadays 3D printing allows manufacturing something we can imagine for a low cost. I usually carry several SD micro cards, enough keys and I love beer,so I thought about a way to integrate all these objects in an only thing. I have designed and printed, in my homemade 3D printed, everything I need and this is the final result!!

Note:
English is not my first language. If I have a mistake or grammatical error I would appreciate the help and I will solve it!! Thanks!

Step 1: Design

The design is easy, with suitable measures to store keys of all sizes, pen drives, 3 sd micro cards and be able to open a bottles with cap.

Step 2: 3D Printing Work

I used blue PLA and an homemade prusa i2. PLA has low wrapping and you can print without heated bed and good quality. It's possible a easy post-process with vapor acetone. SD Card body were printed with 55% infill to give enough strenght and a 0.2 resolution and bottle opener body with 80% fill. The cover was printed with 35% infill to give engouh elasticity and strenght and a 0.2 resolution. You can download .step, .stl and .gcode files!

Step 3: Parts and Preparation

Parts:

4xM3 screws

4xM3 nuts

M3 washers

Pull tab

Tools:

Screwdriver

You can easily buy the parts and tools at any hardware store and recycle a pull tab from a used can. It's necessary to fit the nuts in the bodies, through heat or pressure and to cut two screws to 5 mm. These screws are for opening the bottles and assembly the SD cover.

Step 4: Assembly

To improve the movements of the keys it's neccesary to put a washers between keys, pen drives and bodies. If you need more space you can use larger screws and more washers.

Step 5: Final Result

It's the final result, a pocket size key, sd card and bottle opener with a easy design and printing, low price regarding to commercial keys organisers and more useful.

If you have any suggestions for improvements please let me know!!

    Great project! I really like the microSD holder and the beer opener. I'd like to make one but I think I have too many keys, they won't fit on this tool, unfortunately...

    And just one question: what is the pull tab for? Do you use it as a second beer opener?

    I believe that acts as a keyring, so you could attach a carabiner or something to it.

    Yes Matlek! As StevenY35 has commented the pull tab acts as a keyring but you can put a smaller pull tab if you want. On the other hand I could design a new tool for your keys if you desire. Thanks for the replies!
