I modified https://factorioprints.com/view/-LCAqcogOey-tpXd3wWm and https://factorioprints.com/view/-LC-LC5WUErbhs4Vms5v.
Attach a red wire from the outside poles to any tank, chest, or whatever to get the number of items. It automatically shifts from K to M, etc.
Also, I modified the Clustorio item counter to look much nicer (for me).
