Cassette Tape Storage Containers!

Being massively ADHD, I often have trouble organizing things. One of the most useful ways I've found to keep things less messy is storing everything in nicely-labelled drawers.

Unfortunately, being poor, I lack the ability to buy 3,391 sets of nice, well-built drawers for everything I own. However, I frequent thrift stores, and I saw these old cassette tape drawers for $2 each one day. I bought a bunch, and tried 'em out, and much to my delight, they work nearly perfectly. One problem, though, is that since they're designed for cassettes, the drawers lack sides, and so things tend to fall out.

At first, I put things like tupperware containers and little pencil cases and such in them and made little cardboard sides, but this got more and more complicated with the number of items in each drawer. Since the drawers already have all of those little dividers, I thought I'd try making little boxes that would slot in like cassettes.

I could and should have designed them in Fusion360, but I was being stubborn about it, as I Strongly Dislike™ Fusion360, and it was being super buggy and laggy at the time anyway. So I ended up using Microsoft 3d Builder. I do not recommend doing it this way. While 3d Builder is powerful and simple to use, it tends to lack a lot of features that would have made the process much easier, and subsequent revisions would have been a lot easier to do....and I would have a lot more hair left.

I went through a couple dozen different variations, each progressively better and worserer than the last set, until I finally settled on these ones. I haven't yet figured out a good way to put a nice label on them (they tend to just peel off), so I've just been using a sharpie for now. I've got some ideas for how to do it in the future, along with some other plans, like multi-height boxes that take up more space, bevels, large open containers, Gridfinity compatibility, etc.

I'm pretty sure I've gotten the tolerances down right by now, but they might need a tiny bit of filing or sanding in places to fit together without getting stuck, depending on your printer and settings.

The one with all of the holes is designed for 6x8 neodymium magnets. They should fit snugly, but still come out relatively easily.

The hex driver box has holes for the same sized magnets, but they are not designed to be removable, and they're quite difficult to get in. I had to use pliers and squeeze 'em in, and ended up sorta denting the side of the boxes in the process. This'll be fixed in the future.

Thingiverse doesn't have an option for the CR-10 SE, which is what I printed most of these on, but some were printed with a CR-10 Mini, Ender 3 V2, an Ender 3 V3 SE, a CR-6 SE, and an AnyCubic Kobra 2 Neo. I've also printed at least one box in the following filaments:

Elegoo's Rapid PLA+ and PLA Pro.
Deeplee normal PLA, PLA+, and Rapid PLA+.
Overture Turbo PLA.
3dHoJor PLA+, Matte PLA, and PLA Pro.
Sunlu PLA "Meta".
Kretrum PLA+ (these ones warped fairly often, but I love the color).
Creality's crappy default filament.
eSUN PLA Basic.

Tells you how long these little things have been in "development"! 2 full years, spread out between times where I actually had enough money to try different filaments, get gifted spare rolls, or managed to get a fourth-hand borked printer working.

Totally down for feedback, requests/tweaks, etc!
