Desk Organizer /screws / bolts / Looks like HDD Caddy

I am always looking for a better way to store a lot of things, in this case it's small things. 

I made this part organizer with inspiration from a HHD caddy (cbutters) that I also use in my PC. 

As you can see in some of my bins, I had warping issues, I suggest including some form of a brim raft, and or a textured PEI sheet.

Sized up, removed specific edges, and made completely new bins.
