Module cycloidbox has no class pindiskClass

[knipknap]

After installation from master, I am trying to open this file:

https://www.printables.com/model/45292-cycloidal-gear-box

I see the following in the console:

23:54:04  <class 'AttributeError'>: Module cycloidbox has no class pindiskClass

I now found the sample in the Repository under "Defaultoutput", and when opening that I do not see the errors, so I suspect the linked file on Printables is just no longer compatible.

However, the one from the repository also creates an error, but only when changing a parameter:

00:01:51  Traceback (most recent call last):
