Rhino export to .plt and footwear design



I have a client that wishes to use Rhino for footwear design and production. He is using a Zund lc-2400 machine.

RhinoShoe from TDM seems like a good solution for him, but, unfortunately, TDM is discontinuing development of this plugin. Could anyone recommend a suitable replacement if there is one available?

Also, is there a plugin or method to export rhino files as .plt? So far, I have only been able to find PLT export for Rhino (https://www.rhino3d.com/resources/1611), but it seems to be discontinued and was only available for Rhino 3 and 4.

I would greatly appreciate any help, thank you!
