FilaStash is an iPhone app for 3D printing filament inventory. Every spool is drawn in 3D and shrinks as you print. Photograph a spool label to fill in its details, then log usage after a print or enter a scale reading. Each storage location is a box, and Insights show your spending and colors.
FilaStash is free for up to 20 active spools. Pro is a one-time US$4.99 unlock with unlimited spools, full Insights and iCloud sync.
The builder ships small native Apple apps under LITTLE INSPIRATION LIMITED. Each one solves a single tactile problem, such as filament inventory, without accounts or cloud lock-in where possible.
