Introduction: SD/Key/Beer Opener
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!!
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
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.
