This is my take on filament spool holders. I want it to be easy to change the size and be able to roll the spools out when I want to print with them. That's why I created this modular spool system. However because I wanted it to look clean at the end, the modules don't fit each spool. If you can't find a file for your spool drop a comment with the dimensions of the spool and I'll add it as fast as I can. To make it easier you can give me the size as a 3-number code that you create like explained on the image:

E.g. 467 for Bambulab spools. 

You can print these end connectors If you want to have a clear end like this:
