After having trouble slicing the original model due the the use of 90 cylinders to form a cone shape I modified the OpenSCAD file and replaced it with a cone.

This version should slice without issues in no time.

Alter the OpenSCAD file or just use the STL file to print the turntable holder for your FabScan or other uses.

Note, the parameters may not work correctly due to the modified block of code to insert the cone. If you need to alter the parameters you may also need to change the values that create the cone.
