All of my filament was stored in the cardboard boxes MatterHackers shipped them in with more spools piled around and on top of those boxes. My supplies and tools were in my desk drawers and a small toolbox. It was a mess in my office and made getting at the filaments to change them a challenge. It was time to do something about it.
This is not really a 3D printable object although I have included a prototype STL file I used to evaluate the design and a prototype drawer pull file that I used to confirm my choice of drawer pull hardware.
The cabinet shown is cherry and cherry ply with full extension slide drawers, custom designed filament drawers, and Craftsman style pulls from Horton Brass. The bottom drawer holds larger supplies such as acetone, a couple of boxes of misprints and stuff, and will also hold my printing plates after I make some dividers. The two small top drawers are for tools and small supplies like filament clips, Wolfbite, nozzles, etc. I need to print some organizers for them as well.

Joinery used Festool dominos for tenons and dovetails for the bottom storage drawer and top storage drawers.
