Tool for checking the diameter of some meters filament

I had made a new tool for quick checking the diameter of some meters filament.

I like it! Is it PLA or ABS?

Cool design :slight_smile:

It is PLA
Thanks VEL327 :slight_smile:

Looks nice, but whats wrong with using a regular caliper?

Hi it is nothing wrong with using a regular caliper,
but is mutch faster to check 10m the of filament, so you can see the quality of the diameter.
