<p>This is a case for a Wifi &amp; GPS device meant for Celestron telescope mounts at have available AUX ports. &nbsp;It combines the features of a few commercially available dongles into one device. The full project discussion can be found at <a href="https://www.cloudynights.com/topic/743750-homebrew-wifibluetooth-accessory-for-aux-bus/.">https://www.cloudynights.com/topic/743750-homebrew-wifibluetooth-accessory-for-aux-bus/.</a> &nbsp;The user <i>coollick</i> designed a PCB for mounting the electronics. &nbsp;This case design uses that PCB (tested with version 1.0). &nbsp;The ESP32 is connected to the coollick PCB with headers. &nbsp;(I suppose I could have made it all thinner without the headers, but that would have made securing the ESP32 difficult.) &nbsp;</p><p>The ESP32 is secured to the case with M2.5x4mm screws. &nbsp;You can then attach the coollick PCB via headers. &nbsp;The BN-180 GPS module slips into a thinned, top pocket. &nbsp;3 microswitches slot into the sides to control the different WiFi features. &nbsp;I used a “mxuteuk micro miniature slide switch” SPDT, SS-12F15-G5, found at amazon.</p><p>Two different lids are provided, depending on the horizontal mount hole spacing of the 0.96" SSD1306 OLED. &nbsp;I have a SPI one at ~24.75mm and I2C one at ~23.25mm. &nbsp;You can use M2x4mm screws to secure the display to the lid (or hot glue I suppose).</p><p>The lid hinges into the base and is secured with two M4x8mm bolts and nuts (in captive pockets). &nbsp;On the backside, there is another set of M4x8mm for future mounting options as well as slides on the sides for potential clamps.</p><p>Designed in FreeCAD.</p><p>Printed fine for me at 0.2mm.</p>
