The assembly can be used to control something using wifi; as a clock or a weather station; as a photo frame. There are a lot of ways how you can use a ESP32 microcontroller with a TFT screen. There is a lot of information about it in internet, so I don't give you any schemes or software here.Assembling instructions and demos can be found here:https://www.youtube.com/watch?v=HlH_bMmJlYQThis work is licensed under a Creative Commons (4.0 International License) Attribution—Noncommercial—Share Alike: You may publish remixes of these parts for other models of TFT screens without my prior permission. The maximum dimensions of a TFT screen that you can put inside this monitor are given at the end of this description.You need to download and print all the files from the standard version, except CRT and FRONT-GRAY-FRAME, they are replaced with the files from this remixThis is my first project with a ESP32 and a TFT screen. I've bought a 2.4 inch TFT (https://www.aliexpress.com/item/1005006175348041.html) because it is simple to connect it to the ESP32 (SPI interface with 8 pins only) and it has proper dimensions to put it inside the model without much extra work. It doesn't need soldering, all you have to do is to connect pins with female-female jumper wires. However, I admit that it looks slightly weird because of its small size and a 2.8 inch TFT would look better inside this model. If you buy a larger screen, this would be most likely a bare screen without a PCB with a ribbon cable, and you will also have to buy some kind of adapter for it to connect it to a microcontroller. There are also larger screens with a HDMI interface that can be used with a Raspbery Pi and can be installed inside this model. I think I'll try to make some experiments with larger screens during next winter, but now I don't have much time for it so I use the screen that I have.Screws: optional 2.5x10mm (4 pcs to fix the screen). Alternatively, hot glue may be used.TFT24-CRT: 0.2 mm layer, 0.4 mm nozzle, color black.I recommend to set bottom layer flow 1.05-1.08 to make it stronger, as there will be only one layer around the TFT screen (it has to be thin to be "invisible"). The place for the PCB is 1.2 mm larger to all sides, this is because the PCBs of the same model but produced by different manufacturers or in different time may have slightly different dimensions. You need to align the PCB with the TFT hole looking at the front side and then fix the PCB with 4 fixers. Do not screw them hard because you may damage the first layer of the part if you press on the PCB hard. Fix it just enough to prevent the movements of the PCB inside the part. Alternatively, hot glue may be used.TFT24-FRONT-GRAY-FRAME: use the same settings as recommended for the non-TFT version. For different TFT screen owners.Generally, you can use any TFT screen that fits within the inner dimensions of the FRONT part, but you will have to modify tft24-crt.stl and tft24-front-gray-frame.stl to fit your screen. I also attach STEP files here so that you can easily adapt my parts for some screens that look alike but have slightly different dimensions. Max dimensions: 81.95 x 66.20 mm (77.95 x 62.20 with rounded corners).Viewable area: 66.50 mm x 49.50 mm (62.50 x45.50 with rounded corners).
