You can buy these for a few bucks, but why buy when you can use your $6000 laser to make one yourself?
You would not want to fully load this, or you’ll never get the bits out. It just looks better if you print them this way. Make it as big or small as you need - I included a single but you can just edit the file as you see fit. I assembled my most used bits for this particular bench and this size worked nicely. It’s Amazon box, 5/32 Maple ply, and 5mm craft foam, laminated with Elmers clear craft glue.
