Functional Prototype 3D Print Design

I need a seasoned 3D designer who can create a model for a prototype that I will 3D print. I have a Raspberry Pi and some antennas that need to be housed in a 3D-printed enclosure. I have a Creality Ender CR-10 printer, but have little experience setting it up and using it. I need a designer and consultant who can design the needed enclosure based on the microcomputer components specification, help walk me through actually printing it on my 3D printer step by step, and recommend appropriate materials as needed. The design does not need to be completed on any specific software.

Key Requirements:
- Expertise in 3D design software
- Proven experience in creating prototypes for function testing
- Understanding of 3D printing processes and materials
- Willing to teach using a Creality Ender CR-10 Printer

Please include examples of previous prototype designs in your proposal.
