This model makes it easy to make a barrel knot.

Because the tool is by necessity very small it is recommended that if you are printing only one to use a brim. However, if you are printing multiples, I've engineered tabs to make it easy to remove the brim.

There are three different files:

1. The tool by itself
2. The tool with a simple tab frame added for filling a build plate
3. The tool in a 3x3 grid of engineered bed adhesion

I show the process to design the tabs and more details about the files shared in the associated YouTube video.
