D1 Mini Keychain Case

thingiverse

I was looking for a straightforward, tough keychain case to haul around a Wemos D1 Mini board. After spending a Saturday afternoon messing around in TinkerCAD and test printing, I finally came up with this. It's not fancy. It has decent clearance around the USB receptacle and the reset button can be pressed with something like a pen or pencil. I included two versions... the solid version and the vented version. You can use either base with either cap so print whatever you want. UPDATE 2017-09-27: I've uploaded a new version of the design. This one includes a more secure connector and has the wifi logo embedded in the base and the cap.
