Ender 3 Spool sleeve flanger spacer

Hello !
That's my first project - I know is simple but works well.
It's spool sleeve flanger spacer for Ender 3 and others with spool holder diameter about 32 mm (I have 31,7 mm) and spool hole inner diameter about 53 mm (I have 52,8 mm).
It helps spool to roll without resistance and filament comes smoothly.

You need two of it and one spool extension (short or normal version - depends of spool) ---> https://www.thingiverse.com/thing:3138197
