Phone case designs with working gears, that demonstrate simple mechanical principles. Designed for Iphone 4/4s/5/5s/, more files for other phones will be available soon, like Nexus, and Samsung phones.

These phone cases were printed in Prusa I3, with a 0.3mm nozzle (brought from mixshop.com). NO SUPPORT NEEDED! EASY TO PRINT.
All components fits nicely without any need of polish. Remember to set a higher temperature for first layer to prevent the edges from curling and maybe add some brims. Pins have to be glued on, instant glue works well for me, and it never comes off.

Do you have to print it at 101% for ABS?

Great! I also liked your choice of colors. Changed the wording on the pistons.
Printing on my Replicator Dual, it came out a bit small, but 1% bigger was a bit big. I saved both.

Have to retire them now since I traded in my iPhone 5 for an iPhone 6.

What did you use to change the wording on the pistons?

I first tried to import the files into Sketchup (the free version) and edit them. But I'm not that good at Sketchup, and was having trouble. My son said it would be easier to recreate the parts in Sketchup, so he did that for me.

I'm not using this case now, since I have an iPhone 6. But it was fun showing to people for a year or so. It came apart a few times, so I had to re-glue the pieces.

how do you 3d print things on here

found out how. If your on a mac on makerbot desktop. Download the zip file to your desktop then double click on it then it will have a new file with all the parts. Hope this helps

I'd love that double piston case for my Nexus 5. Any updates on files for non-iPhones? :)

Just uploaded double piston one for iphone 4, named: iphone4_case4

Is the double piston one out for 4 yet?

Double gear one for iphone 4/4s please. I figure you have it already?

Nexus 5... +1 pls
nexus 4 for the wife while im asking

You must have used PLA because these do not fit when printed with ABS.

I printed with ABS and it fits just fine

Please do an IPhone 6 the molds got leaked. So that you at least have a prototype when the 6 comes out so it won't take as long. I will support you on kickstarter and get you as much publicity as possible! ????

Please do a Nexus 5, even though I find it one of the better phones it is practically unknown to half of civilization so if you would please...

Thanks, appreciate the update :)

Any chance of getting dxf files of the gears for laser cutters? I can build iPhone cases with a laser Thanks!

design 5 for iphone4/4s is uploaded now!

Sorry to miss that, its there now. the pin is actually the same as one from case 4

Exact missing the pin for Case 5.... can share?

Where is the pin for Case 5... I printed it all out but no pin to hold the center gear in. Snapping them together would be an awesome video also.
