3d Printer Filament Scale

Welcome to my Filament Scale project. I have had this mounted to my Taz5 for over a year
and have been quite happy with its operation and accuracy. There will be some error because of the pulling of the filament but it gives me a good idea of how much filament I have before starting a project. I've included a wall mount or it could be used as an adapter for a different printer.

The parts were printed out of ABS at 25 percent fill. Nothing special but you need to be able to print accurately to receive the 608zz bearings with no problems. The support arm rotates on the bearings to contact the 3kg load cell mounted vertically.

The electronics would be the hardest part and you need to have a little experience to get that done. It uses a ESP32 Dev board displaying on a Nextion NX3224T028-011 display. Power comes from the micro usb cable plugged into your computer or from an adapter. You need to follow Andreas Spiess #170 youtube video to get Arduino to compile the code proper
