Stop losing the models you meant to print.
Spool is a free library for your MakerWorld finds. Paste a link and it fills in the picture, title and maker. Queue it in the order you'll print. When it comes off the plate, log how it went, photo included.
No passwords, nothing to fill in. Installs on your phone like an app.
How it works
Save it
Share a link from MakerWorld or Bambu Handy into Spool, or paste it. The picture, title and maker fill in for you.
Line it up
Drag models into the order you'll print them. The urgent one goes to the top.
Note how it went
Good, needs work or failed, with a photo and the filament you used, so you never repeat a bad setting.
Cooled fast, 0.2mm, no stringing this time.

Spool installs straight from the browser. There's no app store download.
Android
- Open Spool in Chrome on your Android phone.
- Tap the three dots, then “Add to Home screen”, then “Install”.
- Open it from your home screen. It runs full screen, keeps working when you're out of signal, and shows up in the share menu so links from MakerWorld or Bambu Handy come straight in.
iPhone
- Open Spool in Safari and tap the share button.
- Choose “Add to Home Screen”.
Everything works on iPhone too, apart from receiving shared links from other apps — that part is Android only. You can paste the link instead.
Your library is yours
What you save is tied to your account and visible only to you. Nothing is sold or shared, and you can take everything with you — or delete it for good — whenever you like.

Common questions
Yes. Spool is free to sign up for and free to use, with no trial and nothing to upgrade to.
