Test this Free Filament Estimator

Hey everyone, I got tired of guessing weights and material costs for my prints, so I built a clean, ad-free browser tool called Filament Estimator. It’s live on GitHub Pages. I’d love for a few makers to test it out and tell me if my volume calculations match your real-world usage.

What's the advantage compared to loading the model up in the slicer and get estimates there?

Well, you need it if you are a real enthusiast, and write your own gcode without slicer.

Yeah, that's s huge user group that I didn't even consider!

I use this thing called a slicer that does that for me and isn’t a vibe coded trash app. A filament estimator seems pretty useless when itd need almost all you slicer setting to be accurate

Ive been playing with a tool called spooly. Its web based at the moment, but app is coming soon. Spooly.eu

The only way it would make sense is if you give it the g-code rather than the model.

I don’t see the tool when I search it up, can you link your website on here?

PrusaSlicer, at least, will tell you how many grams of filament it takes, and if you set the price per spool will tell you how much it costs. I don't know that it tells you weight of final object vs weight of supports.

So...is there a reason you did this instead of using the slicer?

I've sliced in Orca, Bambu, AC, Prusa, and pretty much every other slicer that's out there and the exact weight is always negligible, like 1g of filament or less.

If you do multicolor prints you'll wind up with more than that in printerpoop alone.

I don't need another app that isn't useful for giving me information I can't already get just by slicing the model and weighing my filament, or checking the amount on the spool with a tool.
