These inserts are designed for the small Trusco T-15 toolbox.
This model is designed for the Klein Mini Ratchet, ¼" hex bits, and Husky ¼" drive sockets (I bought mine individually, so they might not match the set - I included the .f3d file if you need to adjust sizing). I also have holes on the bottom to fit 5mm magnets to help hold the sockets in place.
Also, I included a blank to design your own inserts!
The author marked this model as their own original creation.
