Random Gravity Falls drink bottle design that I whipped up for the start of the school year. All images were colouring pages from google.
Measure your drink bottle.
Shrink or Grow the image size to the size of your drink bottle.
Change the name to the name you need.
Go to processing.
These settings are for 20W laser, and my optimum settings I always use for all drink bottles (without pretesting each colour)
