Filament length indicator+clip
thingiverse
I got envious with the spool filament indicator. So I created a custom one for my spool. I use this calculator: https://jscalc.io/calc/1Cj6c1zxnr4q8Tzw. This is the clip mix I used (you can print any clip and glue the filament length spool estimate): https://www.thingiverse.com/thing:224791. Before gluing, make sure the top line indicator meets the full length of the 1kg filament. We need to adjust the size of our full spool 1kg as accurately as possible for resizing. Here are my spool's dimensions: Inner diameter = 78mm Outer diameter (full 1kg) = 186.8mm Width = 55.8mm Unit used is meters (m).
