Always in need for a few rubber washers or gaskets so I created a few from TPU to have laying around. Beauty of a 3D printer is with little things like this there is no longer a need to go to the hardware store!

Download and resize to your needs I have created different widths but these can all be scaled to any thickness or size needed.

Here are some minor settings I used to avoid TPU stringing:

• Set to avoid crossing walls 
• Set to print by object
