Yet Another Case for DSTIKE OLED WiFi Deauther Mini

thingiverse

I designed a compact case that can accommodate the DSTIKE ESP8266 Development Board WiFi Deauther Mini with 1.3-inch OLED Display, as small as possible. Maltronics.com and Amazon both sell them, and I'm sure other retailers do too. The case also holds a 3.7V, 500mAh LiPo battery (https://www.adafruit.com/product/1578), but it has to be removed from the case to disconnect it. With a battery, it's a completely self-contained unit, as small as many key fobs. I added little flexible tabs to activate the switches. There isn't space for an external antenna in this design, but the stock wire antenna is surprisingly strong - much stronger than the built-in ceramic bar. The case is thinned over the status LED, but if you print with opaque filament, just drill a hole there. You can see the WiFi status LED next to the vent area. There are two versions of the top/face shell: one with and one without a hole for the auxiliary LED. As an annunciator, I didn't want it flashing brightly, but those who want it as a flashlight will find OLEDTop2.stl has a hole over that LED. I routed the antenna cable so I could use a drop of hot glue to hold the base in place and another drop to hold the antenna. Be careful with the antenna lead when you assemble the sandwich together - mine likes to get trapped between the WiFi module and the case during assembly. Three M3x12 screws and nuts hold it together. I used a little tape to keep the battery away from the circuit board. I was going to make an even thinner back shell for this, but the battery connector is almost as tall as the 500mAh cell I used, so no gain without removing the battery connector. Without a battery, it has to run from the USB connector, and the body of the cable connector is also about that tall. So it's not thin - 14.5 mm. This case has small features, and my slicer really didn't want to fill in between inner and outer shells. It took some trial and error in the print path preview to get something that at least looked like it would be sturdy.
