Anycubic Delta tower "big" screw head regulator

In the process of adjust the towers is more efficient for me make it with the fingers, and the screw head is too small.

This cap, fit in the head of the original screw.

This piece is small but make the level of the towers more fast.

Include the file in freecad, please feel free to modify it.

PD: Add a new model 2mm more diameter.
