15-Compartment Interlocking Small Parts Organizer Shelf Rails

I wanted to create a small parts organizer rack similar to the sortimo system used by Adam Savage, but for much less money.

I've been using these 15 compartment organizers available for around $10 for a two pack. They are sold under the HDX brand, and as "Hyper Tough" at Wallmart.

• Walmart: 15-Compartment Interlocking Small Parts Organizer in Black (2-Pack)
• Wall Mart: Hyper Tough Heavy-Duty Interlocking Organizer 2-Pack

The shelf I'm using is a Iris CX-2 and can be purchased from a number of retailers for around $30.

• Home Depot

It's about the worse you can get as far as low quality particle board furniture goes, but it was cheap, the perfect size, and I don't have the ability to cut plywood in my city apartment to build a nicer box.

The screws are 3/4" long #8 Phillips head wood screws.

Notes:

I also set top, bottom, and perimeters to 4 layers. Using these settings I as able to print 4 sets of rails with a 1 kg spool.

Construction

The rails are designed specifically for the 15-compartment organizer boxes mentioned above and have small recesses that match with protrusions on the underside of these specific containers. So when the containers are inserted they kind of lock into place rather then sliding around freely.

Tip: Drill pilot holes before assembly the box

There's very little additional clearance in this design, so it's important that the rails are positioned accurately. It's a good idea to spend time carefully measuring the layout and drilling pilot holes. It's especially important that the holes for each rail are in line with each other.

Installing Rails

If you use the same Iris CX-2 box that I did be careful not to overtighten the screws and strip the cheap particle board.

Tip: Lip Between Rail Sections

If your pilot hole are not perfectly in line you might end up with a lip between the two sections that catches on the bottom of the container. If this happens just use a knife to trim this down.
