This is by far my favorite AMS compatible spool. Features include:

-It prints well in most filaments with minimal infill

-designed for plenty of weight so it'll work on the AMS rollers

-pretty much matches the BBL spool's sizes so it won't be too big or too small in the AMS

-Its also got a basic capacity indicator to see how much filament you have left in 250g or 1/4 increments

-Has slots on edges for holding end of filament

-will fit BBL refillls

-has starter hole in core for filament

This is a pre-organized set of plates with profiles already done so you can just load up your filament, and print.

If you have lots of filament odds and ends, use them all and make a spool to replace a cardboard spool!

Since its a large functional part, you can get away printing it at a decent speed and even with generic filament that hasn't been calibrated as long as you still have good bed adhesion. 0.2 layer height is fine for a good snug fit. 0.1 isn't really needed unless you just need a smoother sliding lock. Higher layer heights may result in too tight a fit, so please be mindful. If you like this printable spool, check out chenwei's other accessories - https://www.printables.com/@chenwei_679522/models
