Stern-Wheeler Filament Buffer (customizeable)

You can set up your Stern Wheeler sizes, Number of Filaments and Mounting options on onshape and export all the files in your selected configuration directly.

You can also create your own modifications or add your specific mount for your own needs.  To do this, either make a copy of your profile directly in Onshape, or download the *.step files and make the modifications in the program of your choice.

I've also added some mount examples to select that you can use, modify, or recreate.
