Printables Download Counter

The ESP8266 (ESP-01) based download counter offers a web server to set the count. After plug in power supply, the device displays its IP address to open by a browser. The count input will displayed in two ranges (0 to 99999999 and 100.000 to 2000.00 M). Additionally a selenium python script reads out your Printables profile to transfer the download count automatically.
