I was having some issues with print alignment so I made this to test my setup and express frustration.

Printing Notes:
The Screw won't fit at 100%
I ended up printing the screw portion at 85% X 85% Z, left the Y at 100%

Used a standard U thickened

For the screw I used tinkercad, utilizing a threaded section, a cone for the tip, another cone for the head, and for the plus sign on top I used two half moon pieces to make the "hole"

I created a "hole" using the screw in the U - tinkercad.
