Filament Spool Meter

This neat little meter is a super easy way to check the remaining amount of filament on the roll. I was just estimating and hoping but now I can just check and make sure I will have enough for a print. 

 

Just sit it on top of the roll and line up a mark. The small marks are 100s and the big lines are in 200 gram increments. 

 

 Quickest and easiest way to check filament I have come up with yet. Works perfect and looks great.
