While searching for the perfect spool holder to mount under my stairs, I tried several different prints, but none of them felt right. So, like any proper basement nerd with 3D modeling software, I made my own. This Boyo holds two spools and will make your filament storage woes a thing of the past!

I print it with 4 walls and a decent amount of Gyroid infill, but you can do whatever you want. takes my Ender 5 about 4.5 hours to print with the settings listed above.

it mounts on the wall with countersunk screws, but they do not need to be very long. 

if anyone has any ideas for improvements, let me know! this is the first model I've uploaded, so I'd love to hear feedback!
