 Possible reasons


The latch structure is difficult to insert

Inserting into the wrong side


The concave side is the outer side of the spool, and the smooth side is the inner side of the spool.

When changing filaments, the remaining filaments are scattered

Change filaments without using up

It is recommended to use half or more before replacement. Before changing the filament, use a band to pass through the hollow part to bind the remaining filaments.

The latch structure is difficult to pull out

Harder to hold by hand

Use tools, or use greater force to press and pull out
