Wemos D1 Mini Relay Case

thingiverse

I needed a custom case that offered easy access to VCC and ground pins, so I designed one specifically for the Wemos D1 Mini and Relay Shield. The existing cases available were nice, but they lacked a snap-together design that would eliminate the need for screws and nuts. To meet my requirements, I created a case using PLA that provided a snug fit with tight tolerances. When closing the lid, you can feel a satisfying "snap" as it clicks into place. One minor issue I encountered was the reset button, which required some finicky adjustment to get right. To avoid this problem, make sure not to overcrowd the board over the button before snapping the case shut. I made an update on December 4, 2017, to increase clearance for relay connectors on the top cover of the case.
