Parametric Potentiometer knob

I've already created a potentiometer knob but it was very basic and now with this new version you can change the diameter of the potentiometer shaft and all the design change with it.

The default dimension of the potentiometer shaft in this design is 6 mm ( I choose this because is very common) but if your potentiometer shaft has a different dimension just look at theese istruction:

ISTRUCTION:

- SOLIDWORKS:
1) Open the "Potentiometer Knob.SLDPRT"
2) Tools --> Equations --> Change the only global variable there is (Look the picture for better understandig)

- FUSION 360:
1) Open "Potentiometer KNOB - Fusion v1.f3d"
2) Modify --> Change parameters --> Change the only user parameter there is to the dimension of your potentiometer shaft

- YOU DON'T HAVE A CAD SOFTWARE?:
1) Write me in the comment what is the size of your potentiometer shaft and I will upload a .STL file with the dimension you need as quickly as possible
2) Easy enough? ;-)
