Hey, noob here. I want to either print out sheets of .6, .73, and .88mm and then use this hole puncher I got that is designed to punch picks from credit cards, or just give someone a CAD file to print me a bunch of picks individually. My question is, can I just give someone a file and they can change the thickness? Also which of my options i listed above would be cheaper?
Also I would like to put the raised grip style like Dunlop makes, would that be easy to do, or could I just show some 3D printing business one of my Dunlop picks and they be intuitive enough to add it to the CAD pick file? Could they take a basic file like one of the 2 I linked at the bottom and make it whatever thickness (.6, .73, .88mm) i desired?
ALSO, would it be more cost effective to just have one of these made up?

Sounds like you're in need of two separate things, some basic CAD work AND a 3d printing supplier.
If the 3d printing supplier has decent CAD capability, and they offer that kind of thing, they should be able to change the thickness for you. This might or might not cost extra depending on your relationship with the 3d printer people.
However, if you're creating your own or having a file generated for you already by someone else, it should be a simple matter for you to provide the thicknesses you want to the 3d printer people and maybe save some $$.
Raised bumps are no problem either, they just have to be big enough that they can be formed properly by the process. Most SLA and SLS 3d printers will have scan layers .003 to .005 thick so if a bump is very tiny it might not come out how you envisioned. Small bumps in SLS or SLA tend to look like little tiny stepped pyramids, you can see the scan layers (which as a guitar player myself sounds grippy and awesome).
The good news is the printing you are looking to do is usually based on part volume (which translates to build height) and machine time. A sheet of guitar pick thickness will print very quickly! My recommendation would be SLS process with Duraform or similar material (nylon and quite durable).
Your last question doesn't make sense to me. Of course you can have a pick case 3d printed, but it will cost what it costs on top of whatever you're spending for pick thickness sheets of material.
If you have a connection in the 3d printing world, I can see you getting these parts for a deep discount or free even, the SLS process usually starts the build with some geometry called a 'heat fence' that amounts to basically a thin sheet of material. If your guitar pick 'sheet stock' was configured just right so it could be substituted for the heat fence, they would be able to make parts for you out of what is normally throw-away material, which would be cool.
