Snap on the newly printed claw lids to the spool of filament. Notice that they are different heights. Some of the spools are asymmetrical. match the lids according to the Desing of the spool. I also loaded multiple types of lids of various sizes. You can choose between them, scale them or trim them according to your needs. They should click into position and never require glue.  

The lids are having separate designs for L and R. They should be installed in such way that the claws are gliding in a tangential way to the rod. 

Place the spool onto the 8mm rod. Suspend the 8mm rod using the 3D printed arms. For more info on how to install everything check the video and the pictures. 

insert the filament into the extruder and check the movement of the spool on the rod.
