There are many variations of the packout dividers on Printables and Thingaverse, but I created a new model from scratch using OpenSCAD. The reason to create my own model was so I could create custom variations such as the ‘H’ shape for the long bins.
The dividers will be functional when printed at 0.30 layer height, but will look better at 0.20 layer height. Use a brim unless you're really confident in your buildplate adhesion. Don't print in PLA if you keep your organizers in your vehicle.

The author marked this model as their own original creation.
