This is a small Filament holder, that allows you to take 100 mm of filament, and make
10 readings to obtain an average diameter of you filament for your slicer settings.
Included is a simple spreadsheet to enter the reading and calculate the average, and also to store you filament and printer settings.
Hope People find this usefull.
Printed in PLA Ziro Transparent Purple.

I printed this at 0.3, just to test it out, the holes would print much better at 0.20 .
