The loose is actually a tight fit for the replica Bambu Labs spools I printed. The tight (snooze) version fits the factory spools, but it’s too big for the replicas you print yourself.

Just like the ones that come on the spools. These are great to ensure that you don’t break the end using the pass through holes in the spool.

These look great and work even better. I installed three without a problem and was even able to use the existing screws, though just barely.

Great design led to a great print.

this print came out great. Great design!
