What's New in Spool

1.1.90

October 2, 2026

Spool for Mac. Spool is now a real Mac app. Your inventory, Workshop, analytics and labels, on a screen with room for them. Search for Spool on the Mac App Store. Import from your slicer. Send a sliced .gcode or .3mf to Spool and the print writes itself up from what the file carries: name, print time, filament weight, material and colour. Spool suggests the matching spool and finds the printer in your Workshop. Not every slicer's files can be read yet. The Print Tray. A quiet tray for prints waiting to be logged: sliced files you have sent to Spool, and Bambu Cloud prints you have not logged yet. Log or discard on one device and it clears on the others. Saved Views. Shape the spreadsheet the way you think: choose your columns, sort and resize them, group your spools and total up their count and weight. Then save the whole arrangement as a named view and come back to it. Free, with no limit on how many you keep, and it exports to CSV. Labels and tags. Label Studio gets saved styles you can apply to a spool in one tap, plus vector PDF export for print shops. Spool now reads and writes more filament tag formats. Label Studio and its exports are Pro.

User reviews

Wow, I wish I could find this earlier

Such a well-designed, pretty, and versatile app. Still exploring it, will come back to update with more details.

Response from developer

Glad you found Spool! There's plenty more to dig into, and much more to come!

Best indie app

I usually don’t write reviews like this, but this app is great. It gives great insights for your printing costs and it syncs well with Bambu cloud. It is awesome, and even though it has a sub, it isn’t required and the base app is still great for anyone who doesn’t have a print farm. 5 stars

Response from developer

Thank you for the review! Really glad the Bambu sync is working well for you, that one took a while to get right. And yeah, the base app should be useful without needing to upgrade. Means a lot coming from someone who doesn't usually leave reviews.
