I made this simple but functional AMS Lite Spool Adaptor for TecBears Filaments.

After buying some TecBears PETG Filament i looked for a AMS Lite Spool Adaptor but only found one which printed 3h needed a bunch of filament and did not fit in the end.

My design is flexible enough to compensate the variance in spool diameters of the TecBears filament (which made the other adaptor to get stuck) The TecBears spool got a diameter of 72.60mm on one side and 73.40mm on the other and only god (or someone with better measurement tools) knows what the spool diameter in between is.
