Cereal box mount for Ender 3

I wanted to be able to swap out my cereal container dry boxes easily on my ender 3 printers so I designed this mount to hold the dry box on top of the printer in replacement of the orginal spool holder.
you require M3 or M4 t-slot nuts and the bolt which is around 10mm I think. Hex cap bolts work fine but the flat head type are a tight fit on this.
Make sure all your boxes are build the same way. I made mine so wider part of the box faces the left side of the printer when looking from front.
I have also included some silica gel boxes I designed which fit nicely in the bottom of the box. You need M3 nuts and washers for this 16mm or 18 mm work.
