CNC files from Etsy?

Has anyone bought any CNC files for wood projects off of Etsy? If so how easy is it to convert them to use on slingshot and create?

I have used files in the early days but you may have to adjust depending on the wood thickness and size of bit.
The best thing is to check on slingshot if the sizes are correct depending on online, outside and inside cuts( example if you use on line then add half diameter of the bit- more so if using pockets)
I have made a bed side stool for my son but used 12mm mdf instead of 18mm so had to do some manual adjustment.

Good luck.
