Parametric tool rack

Parametric tool rack I designed. I envision using it for sets of small screwdrivers. You can update for your own settings using customizer.

UPDATE: The new version allows for printing without support, and defining different tool slot diameters per row.

Variables are as follows:
min_height - This is the height of the first row.
height_step - This is how much higher each subsequent row will be. Switch to zero to have the rows level (printable without support).
wall - Thickness of the wall
