About this 3D model

A1 & A1 mini AMS spool holder liner Originally, the liner size on the spool holder did not fit. So I simply made one myself. Later, I had a sudden idea: what if I could add a liner directly to the third-party filament spool and have it work normally in the AMS? After trying it out, I found that it does work! There is no latch structure, you need to use 502 glue to attach it to the spool. The inner diameters of the spool on both sides are different, so pay attention when installing. This one I made is disposable, and two are needed for one roll of filament. Considering the printing time is not long and the filament consumption rate is almost negligible. This can avoid the long waiting time of printing the Bamboo spool. The two inner diameters are 72.5mm and 73.2mm respectively. It can also be used on the fixed bracket of the spool holder.
