This is my first try at dualstrusion. I embedded a little charger icon in the lid to give it a little more flash and to quickly orient the side with the usb jack.The new sliding mintycover has a much thinner tab, which makes it slide much easier around the track! The lightning bolt detail is pretty thin, so select 0 shells on both files to get it to print correctly.Download all three files. Using RepG, merge the two mintyboost_charge files. The logo file will be the constrast color. Set shells to 0 for the best lightning bolt fill. Print out one of the mintycovers- make sure you print it out slanted (helps with durability). Buy a Mintyboost from Adafruit: https://www.adafruit.com/products/14. Get a battery holder that loads from the side like this one: digikey.com/product-detail/en/BC22AAW/BC22AAW-ND/66727 Assemble the MintyBoost inside of the enclosure, insert a mintycover into the track, and snap the lid into position.
