Revised rating and comment: These did print perfectly for me and attach perfectly to the Bambu spools. They are simple and effective at holding the filament. Clearly didn't RTFM on attaching them to the right side of the spool so have revised this comment and rating, I've also left the original below as a sign of repentance and apology to the designer who was polite enough to point out my own stupidity! Original Comment: This works well enough, but I find it jams up in the AMS which means you have to take it off. At that point there are better options to quickly add/remove to the spool. Great for storage, less so for active use.

EDIT: Posted the wrong pic/rating before. This this is perfect to trim PTFE to the right size, sure you could do it by hand, but this means they are cut square and consistently to the same size AND you don' thave to find a cutting mat!

Works perfectly and stops me putting a calbe into a port that does work.

Simple but effective. Love it.

I use these to soak up purge because colour doesn't typically matter. Then they are awesome as desiccant holders, but I have a few with bolts inside I use as spool weights at the end of a spool so the AMS stays happy.

This thing is awesome, uses very little filament and kids (and adults) love to build and play with it.

This one is an easy print, goes together pretty well and a bit of lube makes things work. My only issue has been (probably me) trying to make it go too fast and the gears can start to separate. Keeping it slow and steady works a charm.

I made a bucnh of these for the kids at school who love them.

This one fits in beautifully with a bunch of similar things I've made for fidgets.

Comes out pretty nice

excellent use for a spare fan. Definately better than a commercial $5 usb fan... or at least a great conversation piece!

Nice coaster holder.

I love this thing soooo much. Everytimg I get it out I point out how awesome it is to my Wife... (which she is coming to hate :P )

I've bene meaning to print something minimal like this for my wallet for ages. Quick and easy print.

I'm loving printing coasters with the AMS and having a black cat as well this is perfect!

I needed to ship my old Apple Pencil to a new owner and was wondering how to package it and had the brilliant idea to use my 3D printer! This model looked awesome and was an easy 2 hour print (without the multi colours). Came out perfectly off the bed, holds the pencil securely and is now on the way to it's new owner. I forgot to take a good photo of this one but here is one off the printer camera.

A great little test of a new nozzle.

I love my Homer coaster, it's well used and very easy to clean up.
