3D printed dividers for the Craftsman 30 Drawer Multi-Use Cabinet that I purchased at Lowes.
The cabinet is also available online under the Stanley brand.
Why have two brands sell the same product and only use one exclusively for a given sales method?
Beats me. My guess is some kind of branding that moneys the branded money (whatever that gibberish means; long story short, branding and money?).
Where To Get It
Nothing too fancy, just a measured slab of plastic.
Available on Thingiverse.
Modeled in Blender.
They Don’t Come With Any Dividers!?
Imagine going to the hardware store and looking for a small parts drawer organizer. You find one that looks decent, has lots of trays, decent size, and notice slots for dividers.
Then you look all around the packaging, shaking it to try to hear something loose dangling somewhere – anywhere.
Where … are… the dividers? How many are there?
What!? None? No… there has to be…
Really? None!?
Well, I guess that’s what 3D printers are for.
Designing It
Made in Blender 2.9. The first thing was to observe the tray and gather measurements. This is done by mostly eyeballing it with some help from calipers.
Afterward, it’s modeled in Blender, and a few iterations are performed. Luckily it’s a pretty small piece of plastic, so iteration is pretty rapid.
From there, I cut the depth in half to remove excess material. This cuts print time significantly. I still need the edges to be the original depth to index with the grooves in the tray where the divider should go. I also add a rounded square at the top to emphasize a dedicated area where a label can go.
After getting it to look and fit how I wanted, I put it in the tray, and put the tray in the cabinet. Unfortunately, the divider was slightly too tall and would knock the roof when sliding, so a little extra material was removed, especially at the top corners.
Left) The original divider, just from measurements.
Middle) Making the divider thinner but leaving width for a label area and the edges.
Right) Removing extra material at the top, so it doesn’t collide with the top rails.
I haven’t used the label area for anything yet, but I figure it’s better to have it and not need it.
Others
Edit 02/17/2023: I was searching if other people have done the same.
I noticed a user on Thingiverse, DMorris, posted tray dividers before me. I wasn’t aware of it when I was designing mine, but I think it’s interesting how we both have a tab at the top.
