So now I am getting projects from family members. This is from my dad. He has an outdoor table that has a hole in it for an umbrella. The piece that goes through the table to support the umbrella was old and broken, and you can see where he's tried to glue it back together many times over. So I made him a new one. It was an interesting exercise because I learned how to do screw threads in my cad program. It did take me three tries to get the nut part to mate correctly. I'm learning a great deal about the tolerances of fitted parts from the printer.
