TigerScale
The scale that speaks spool.
TigerScale is a connected scale for filament: drop a spool on it and the apps know what's left, to the gram — and with a TigerTag on the spool, it knows exactly which spool it's weighing. Open electronics, like everything here: the whole project lives on GitHub.
Why you'd want one
The apps already estimate grams from every print. The scale turns the estimate into a fact.
Honest grams
Estimates drift — purges, failed prints, that one skein of ooze. A weigh resets the truth, so a 30-hour print doesn't die at 92%.
It knows which spool
A tagged spool announces itself to the scale — no picking from a list. Drop it on, the number lands on the right spool.
Weigh and walk away
The reading goes straight to your inventory and follows you across devices. No notepad, no mental math.
Open electronics, like the Pod
TigerScale is a project you can build, not just a product you receive: the firmware, the design and the guides are public on GitHub. Print the parts, flash the board, drop a spool on it. And as always — nothing here is required. The apps track grams fine without a scale; the scale just makes them exact.
Quick answers
Do I need a TigerScale?
No — nothing in TigerSystem is required. The apps estimate what's left from every print on their own; the scale replaces the estimate with a measurement.
Can I build it myself?
Yes — it's open electronics. Firmware, design and guides are public on GitHub; the parts are commodity.
Does it need TigerTag chips?
It works best with them — a tagged spool identifies itself and the weight lands on the right spool automatically. Chipless spools can be weighed too; you just tell the app which spool is on the scale.
Where does the weight go?
Into your inventory in the apps — the same grams-left bar you see on every spool, synced across your devices.
How exact is it?
To the gram — which is exactly the resolution a print needs. The point isn't lab precision; it's never being surprised by an empty spool.
