Ultimaker ESP32-Cam

This is a video camera for an Ultimaker 3D printer that utilizes a very affordable ESP32-Cam module, which can be easily purchased from Amazon: https://www.amazon.com/ESP32-CAM-Bluetooth-Camera-Module-Development/dp/B07S5PVZKV/ref=sr_1_13?keywords=esp32-cam&qid=1566655293&s=gateway&sr=8-13 I prefer these modules because they have built-in Wi-Fi and can run a small web server within them. This enables you to access the video images directly using a browser on a MAC, PC, or phone. There are two types of camera lens modules that can be used with the ESP32-Cam: one is a simple 1:1 (normal) lens, while the other is a fish-eye lens. I have provided a case that fits both of these modules. You can purchase a package of three fish-eye lenses from Banggood: https://www.banggood.com/3pcs-Fisheye-Lens-TTGO-Camera-Module-OV2640-2-Megapixel-Adapter-Support-YUV-RGB-JPEG-For-T-Camera-Plus-ESP32-DOWDQ6-8MB-SPRAM-p-1493572.html?rmmds=myorder&cur_warehouse=CN The normal lens must be positioned on its side to produce an upright image, while the fish-eye lens must be positioned with the lens up. This is why there are two different brackets: one for each type of lens. The fish-eye lens works best. An example fish-eye view photo is included, which can be found at the end of the list. The brackets fit on any of the Ultimaker edges, but be cautious when placing them. If you place the bracket on the left, it will likely get knocked off by the print head. Similarly, if you place the bracket on the front of the printer, the print head may press against the camera during a filament change operation. However, I prefer to place the bracket on the front of the printer since the head rarely comes near it. Just move it out of the way during a filament change. I have provided the web server program for the ESP32 (esp32-cam-streamonly.ino). You will need an FTDI interface to program the board using the Arduino IDE. The FTDI to ESP32 wiring diagram is also included. 9/3/2019: I added a fish-eye corner bracket, which is even better than the front mount bracket because it never gets hit by the print head. 9/4/2019: I added a normal lens corner bracket, which is even better than the front mount bracket because it never gets hit by the print head. 9/22/2019: I replaced (esp32-cam-streamonly.ino) file with a newer version that removed unnecessary header files. 9/27/2019: I added an external antenna bracket to the project, which allows you to use an External antenna on your ESP32-Cam. I used Fusion 360 to design this item, and I would like to thank Autodesk for their generous support.
