Hi there,
This is Bogdan from Romania.
I'm a mechanical engineer, 3D designer and modeler.
I could design that enclosure for you, with respect for internal arrangement of the modules, air vent spaces, cabling, etc, and make it easy to manufacture, even in 3d printing for prototyping.
If you need any other details, pls open a msg channel here, and we'll discuss all the details of your project.
Even my bid is a little higher than your max offer (and could raise even more - depends the internal structure of the enclosure and what else attached) I'm assuring you that deserve!
Based on your input - drawings/sketches/indications, I will make a basic model. On this model (upon your indications) I will make different adjustments/modifications/changes in such way that the result will comply with your needs/desire.
When the final model is approved, I will send you all the files for prototyping/manufacturing.
Regards
Bogdan
