Update 2 (11/29/2014): Added team logo(s) to the side; Enlightened (gee, wonder which team I'm on...) shown. I was nice, and made a Resistance version too, I just don't plan on printing one... I was also having a problem with one end of the battery retainer lifting off the print bed (always the same end, so maybe my heat bed has a cool spot?) -- so I made bigger "ears" to hold it down; that did the trick. This will also fit an iPhone 4 in an Otterbox Defender case (the width is basically the same); it will just be a little shorter than the battery, and this is a short cable: http://www.amazon.com/Innovative-Digital-Charge-compatible-iPhone/dp/B00DCRX9WE Update: Added Ingress logo; make sure to use the "logo_clip" .stl file. If you play Ingress (https://www.ingress.com), you most likely have an external battery... So, I created a clip that piggybacks an Anker battery (http://www.amazon.com/gp/product/B009USAJCC) with an iPhone 5 in an Otterbox Defender case. The clip latches onto the top edge of the case, and snaps into the notch on the other side of the case, just like the original belt clip. In fact, the entire combination can still be clipped into the Otterbox belt clip. Combined with a 10cm lightning cable (http://www.amazon.com/gp/product/B00B5RGAWY) and some bluetooth headphones, it makes a nice self contained package. There is a slot running the length of the back for inserting a "velcro cable tie" through, forming a simple wrist strap (more of a back-of-the-hand strap). Thanks to my friend, Carl, for that suggestion.You will want to print one "clip", and one "battery retainer. There are 4 different clip files to choose from (of course, you should print #3): The main clip should be printed as-is (orientation), with support. The two "ears" should be cut away after printing; they help keep it stuck to the print bed (it doesn't have a large contact footprint, and the one "end" tends to want to lift). The battery retainer also has ears to keep it stuck to the print bed that should be removed after printing. It fits into the slot on the main clip, and should snap into place (bumps on the inside edges snap into recesses in the edges of the main clip; they may need some scraping/cleanup it's pretty tight tolerances). I used a 13" velcro cable tie (http://www.amazon.com/gp/product/B004C4U1HC/ref=oh_aui_search_detailpage?ie=UTF8&psc=1), any longer, and to would be too long. An 8" one should work.
