IKEA Box SAMLA Spool holder spacer

My spool holder serves up to 4 filament spools on an DN50 (sewage?) pipe. To separate the spools a bit and to lower the chance that one spool turns the next spool I've created this spacer.

As usual I've attached the Fusion 360 file to make adjustments easier for you. You will also find a factory file with the settings from my Prusa MKS2 and PLA from Das Filament.

Side note: I'm new to 3D printing and I've to learn everything. I believe that making things on your own from the very first step is harder but finally you will get things done. Because of that I try not to download lot of things but create them from scratch. Even if they already exists. By sharing those things I hope to get feedback that I can improve my skills. So don't be angry if I upload things which already exists here.

I can't upload Fusion 360 files here, but you can download those from my Thingiverse page: https://www.thingiverse.com/thing:2459579
