Keep a shelf count of fresh (unopened) rolls per colour. You only number a roll when you open it — the farm then auto-subtracts filament as prints finish. When no open roll can finish a print, it tells you to grab a fresh one and which number to write on it.
| Colour | Fresh | Open | Open g left | Queued need | Status |
|---|---|---|---|---|---|
| Yellow | 0 | 0 | 0 g | 1099 g | order — short 1099 g |
| Olive Green | 0 | 0 | 0 g | 73 g | order — short 73 g |
| Almond Yellow | 0 | 0 | 0 g | 0 g | ok |
| Morandi Green | 0 | 0 | 0 g | 815 g | order — short 815 g |
| Lilac | 3 | 1 | 1000 g | 0 g | ok |
Just a count of unopened rolls. Bump it when you buy; it drops by one automatically when a roll is opened.

One-time: for rolls already on your printers, add them with their current weight so tracking starts from the right number.
