Eagle
Using Eagle to drag and drop elements + make layers
Problem with Eagle
Only outputs dxf
We then have to trace as a png in illustrator
This creates a double line
Less accurate + goes over each area twice
Zack defines width of the pumps, but doesn't worry about depth
Width of channel / valves
Too small = hard to align + valves will no longer stay closed
Larger is more robust
Barb spacing
Want enough space between each barb for tool
Far enough from the edge
Prevent leaking from the port
