Simple Eppendorf Holder

This is a very simple mechanism for holding an Eppendorf tube under a microscope at an angle.  It has a small lip which allows you to position the tube on the stage without touching the tube itself.  You can also pick it up and move it around because of the lip.  It is big enough to hold multiple sizes of Eppendorf tubes commonly used, but you can scale it when you print it if you want.  Unlike my Complex Eppendorf Holder, this will allow you to put the tube in contact with the microscope's stage.  Unlike the Complex Eppendorf Holder, this won't allow you to adjust the angle. Again, you can scale the Z axis if you want it different.
