Filament spool drawer holder with no hardware required.

I wanted to stack my spool drawers in a way that does not require any hardware, is expandable and could be easily transported but struggled to find one that would be strong enough so I designed my own

It has been designed with all matching treads all round so can be assembled in any order. Multiple middle sections can be printed to stack as high as needed and expand when more spools are added. Middle plate is not required but allows for individual spools to rotate without rotating all spools at the same time.

Male thread is designed with -0.2mm offset to allow for 3D printing. Tolerance is perfect for my Ender 3V2. other printers may vary

Could still be optimised in some ways but it functions as intended.

UPDATE:
Mid shaft inside chamfer added. Print with thread at top no support needed.
