                                Print warnings
*Neodymium magnets are strong and fragile*

make sure the magnets attract properly before gluing 
Supports are needed only for the stand 
The holder requires bridging
If your printer isn't good at bridging
Print horizontally on a raft
Try to remove any big Imperfections
if you want to take it out of that spool later
bearings are a little tight putting on but work well after assembled
The bearings can be used independently from the holder (and vice versa)
bearing less model coming soon
