I get a lot of hardware from Bolt Depot and it comes in these tiny bags with labels, which are great, but when I’m building products I find that I’m always opening and closing bags to grab what I need and I wanted to try another way. I designed a parts tray with a sliding lid to organize things a bit better.
Here’s a render showing how it fits together. I do this stuff in OpenSCAD. (I’m still far from being an expert in that application, but I am getting better, and exercises like this help.)
It’s a three piece design. There’s the bottom part (the tray) that holds things, a top part which gets attached to the bottom part with screws, and a lid. I laser cut some clear(ish) acrylic for the lid so I could see the parts inside. You could just print the tray part if you don’t need a lid.
No laser cutter? No problem! You can also just print a lid. Obviously you can’t see the contents with the 3D printed lid… though maybe if it were printed in resin? I don’t know… I don’t print with resin. Anyway, there are files to laser cut a lid and for 3D printing a lid.
Part of the idea of two separate pieces connected with fasteners was to allow for making the fit tighter or looser, to some degree. There are friction bumps on the top part that the lid slides against, and the top part flexes a bit to allow for a good sliding fit. That’s the idea anyway.
Now, the first sliding lid I laser cut didn’t fit… seems it was 2.8mm acrylic, not 3mm acrylic. To make it fit right I just added a bit of tape along the edge of the lid. (Note: Clear tape might be better. I used blue tape for this photograph so you can see it.) You can also adjust the top part and print it until you get it right. It’s a small part that doesn’t use too much filament.
I posted the in-progress photos of this on Twitter and a fellow named Pooch asked if I could just print it as a single piece standing up. Turns out you can, so I included an STL for that method as well. (I’m still a fan of printing in two pieces and then using a laser cut lid but hey, options are good!)
Because options are good I also created a “deep dish” version that’s a bit taller and will hold more (or larger) hardware a bit easier. There’s also some OpenSCAD files so you can change whatever you want. So… many… options!
You can get all of the files from Printables.com – Tray with Sliding Lid.

Excellent documentation and presentation of model and object on this site and printables.com. Valuable contribution to the 3D community.
