Sean Charlesworth shared his devotion to Adafruit and the Minty Boost kit through his excellent walkthrough tutorial forhow he created a 3D printed enclosure for his kit, posted at Tested:

I am a huge fan of Adafruit Industries, which was founded right here in NYC by MIT engineer, Limor ‘Ladyada’ Fried and is a supplier of great DIY electronics projects and an excellent source of information. Adafruit hand-picks quality electronic components, designs their own boards and kits and has an amazing tutorial section. I am no electronics wiz and have managed to put together some pretty cool stuff with their guidance. I love this place.

One of Adafruit’s first kits was the MintyBoost USB charger which you solder together yourself, runs off of two AA batteries and fits in an Altoids mint tin. Throw one in your bag and they are super handy when you need an emergency phone charge. It’s worth the looks you get when plugging your phone into an Altoids tin. I’ve built five of these and from those builds thought of two improvements I wanted to make. The first problem was if the batteries were left in for an extended period of time they would eventually discharge to the point that they would leak and I killed two MintyBoosts this way. The second thing I wanted was enough room in the case to fit a small charge cable, so I decided to design and 3D print my own enclosure.

Today I’m going to show you how I approached this project and printed this custom MintyBoost charge pack….

Every Thursday is #3dthursday here at Adafruit! The DIY 3D printing community has passion and dedication for making solid objects from digital models. Recently, we have noticed electronics projects integrated with 3D printed enclosures, brackets, and sculptures, so each Thursday we celebrate and highlight these bold pioneers!

Have you considered building a 3D project around an Arduino or other microcontroller? How about printing a bracket to mount your Raspberry Pi to the back of your HD monitor? And don’t forget the countless LED projects that are possible when you are modeling your projects in 3D!

The Adafruit Learning System has dozens of great tools to get you well on your way to creating incredible works of engineering, interactive art, and design with your 3D printer! We also offer the MakerBot Digitizer in our store. If you’ve made a cool project that combines 3D printing and electronics, be sure to let us know, and we’ll feature it here!

  1. Nice. I added a switch to one I built as well. Another good improvement is to add room for a third AA cell. With three cells the minty boost will almost fully charge the phone, two only get it to about half way.
    Did you upload your design to thingaverse?
