Quick Filament Level Checker- in 18min, only 3.3g

This small, handy device makes it incredibly easy to keep track of how much filament is left on your spool. No more guessing games or crossing your fingers that you’ll have enough for your print — now I can just glance at it and know exactly where I stand. All you need to do is set it on top of the spool and line it up properly.

It’s by far the quickest and most straightforward solution I’ve come across for monitoring filament levels. It works perfectly, looks sleek, and has definitely become a go-to tool in my 3D printing setup!
