Extra-wide bins for Small Storage System

Saw that CaptainObvious stopped making wide bins at 2-wide, and I came across a situation at work where I needed a 3-wide bin.

So I took the original 2-wide, and through some rudimentary Fusion360 skills, made 3-, 4-, and 5-wide, 1-deep bins.

**Note:** Oops! I didn't remember to incorporate helper disks as the Cap'n did to minimize curling, so please add them manually until I update them!
