Good to know you are thinking about itI would I would price them all the same.
I'm not sure to understand what you mean by that though: Same price as the printed version or all the designs would be sold at the same prices?
I don't know, for your Inspire 2 mount I would be ready to pay a bit less than the printed version obviously but still around 30 to 40$ if it comes with the stl for all the adaptors as shown in the pictures
