After starting to build the MMSS by @JorgeRui (Great stacking system), I needed various additional storage blocks as I have various spare parts for my A1, A1 mini and X1C.
So I started making a few in fusion remixing his blank blocks.
This one is for storing hot end fans.
See my other models for other tool storage and spares.
