I designed this because I needed my spool to sit steady on the table, I had issues with my spool falling off the holder.

This was printed on a Flash-forge Guider II, hence the Dimensions, but you can cut the model pieces in half if your build plate isn't large enough.

I printed a second set of hinges which I used as a lock on the opposite side of the case(refer to pic's) . I glued and plastic welded the hinges with gel based super glue and a 3D pen, I used the 3D pen to run a line of filament along the edges of the hinges.

if you want to make the case air tight, just add a layer of silicon on the bottom edge of the spool case cover.

Your more than welcome to modify the case to whatever suits you.

Let me know if you have any questions.

Happy printing
