Added another calculator and guide. 🧮 This one helps estimate how much filament is left on partially used spools before printing.

Cool! If anyone needs empty spool weight info: https://www.printables.com/model/464663-empty-spool-weight-catalog

As of 08/26/25, we have over 200 spools listed 🤯

That's a very nice list, thanks! I will add the link to the guide as well!

Yes, it is. I use it when i want to estimate the leftover filament on a spool, but i dont have an empty spool of that brand. I see you marked me as the contributor (Thanks :D), but as you can see on the link, the catalog is not mine, i didn't publish it on Printables. The author is @Scuk_253012. I don't want to take credit for his work (Sorry for not pointing it out in my original comment).
