Using the Bearing in these rollers rather than metal ones and they work perfectly and save a ton of cost.

I use this for both of my A1 mini's simple and easy to use. great design.

Works great, Using for shelving A1 mini in a small space.

Used for AMS hub. I was without this tool I cannot get the PTFE out of the hub and this allows me to do all 4 in less than a second.

Great design! Printed with Tree supports and came out flawless.

Printed in all PLA, it works great but is very rigged because of the PLA. All clearances are perfect. If you use bambu spools you won't need the two spacers and use the grip washers for the Spool holders to save your fingers. Great for refill spools that tend to get stuck on the sides and hang.
