If anyone wants to generate their own or wants other custom ones generated I can easily do so. I'd need to clean up the OnShape document a little before sharing it but if there's interest I can do so.
The author remixed this model.
I wanted to be able to easily generate bins for the bits I have and at the same time made it so that I can easily customize the letters pre-slicing so that I just have to change the base object to get a different color than the rest of the letters. Each letter in the object is an individual part so the files are on the larger end.
