Please help with this… i’m no designer.
Here I share a 3D model (Autodesk Fushion360) of the whole enclosure for the Controller v4.4.
It’s not exactly what you are looking for but may help somehow. Of course you can generate a STL file inside Fushion360. I used it to 3D print this enclosure for my BMS:
Thats an amazing work. looks really great. Would you may consider to share an *.stl file, that it can be printed?
