Spool holder by Moku system

This is a spool holder by Moku system. Please raise your hand if your desk is messy. So do I. My desk is also messy. I hardly have any space left to put a printer. That's when I turned my attention to the desk organizer "Moku system". Those were revolutionary for me. After using the Moku for a while, I wanted a spool holder. I searched for one, but surprisingly, there wasn't one available. "There seems to be a demand for this. Okay! Let's make it," I thought, and this is what I came up with. How to assemble&use: Just put the upper part on base part. Due to my skill level, there are directions in which it fits well and directions in which it doesn't. If you try it and it doesn't work, rotate upper part 180 degrees and try again. The printed model may not slide smoothly on the rails as is. This is often due to support marks. Please sand them down and try again. Gif @ from Tenor Filament clip that I used at picture: https://makerworld.com/ja/models/407145-the-universal-filament-clip?from=search#profileId-309226
