I have a couple parts bins that I got secondhand, but none of them came with dividers. I couldn't find any existing drawer dividers online that matched my bins, so I did my best to measure and adjust the dimensions accordingly. I noticed that my two different parts bins had drawers that were roughly the same dimensions, and my final divider design fits well in both.
These drawers are slightly tapered, either intentionally or due to deformation with age. As such, the drawer divider needed to be slightly trapezoidal. I added a little lip a the top for easier grip. For reference, the drawer is about 111 mm at the top and 108 mm at the bottom. The bottom corners are clipped to fit a rounded bin. I chose a divider thickness of 1.2 mm for a good fit without being too tight.
This model is relatively simple, but it took some adjusting and several iterations to get a divider that fit both of my drawers well enough. I printed on the standard A1 mini preset with 0.2 mm layer height (it's a solid part with no infill). Each divider consists of about 8g of material and printed in around 15 minutes on my printer.
Update 2025-11-05 - I've been organizing more parts and I needed to print more dividers. I was inspired by another model that used a hexagonal hole pattern to save some material, so I modified mine accordingly and reduced material usage by about 30%. Also, the fit was just a hair too tight, so I reduced the top width of the divider by 0.4mm and scaled accordingly. The resulting model is a nearly perfect fit taking just under 6g of material (depending on your slicing). I've added the slightly narrowed and reduced material model. Please feel free to reach out if you want me to add any other minor adjustments!
