Readme.md confusing

[jmartinz]

In tje readme say:
All models are in the box_frame folder, "including models for aluminium single plate". For some common configs we prepared models, see box_frame/sample_stls.

Please, if now models from single_plate are maintained in https://github.com/josefprusa/Prusa3-vanilla, remove the "including models for aluminium single plate" as it is a bit confussing.

thanks

Models for aluminium single plate are both in Prusa3/box_model AND Prusa3-vanilla, and they are quite different. The models in Prusa3-vanilla have different x-carriage, different extruder, they dont use tensioner and there are many more small differencies.
Thats why there is the second paragraph in the readme.
