Fusion 360 Parametric Enclosure Design for Working Prototype

I am using Fusion 360 to design a compact electromechanical device. I have already designed, 3D printed, assembled, and tested the primary functional structure and now need assistance completing the remaining portions of the assembly using proper parametric Fusion 360 design practices.

Attached photos show:

- the current working electronics prototype
- the electronic modules requiring mounting locations and enclosure integration

The main functional structure and Fusion files will be shared with the selected designer after NDA agreement.

The electronics system is already functional. This project is primarily focused on enclosure design, mechanical refinement, and modular assembly features.

CURRENT HARDWARE INCLUDES

- ESP32 board
- OLED display + rotary encoder module
- RTC module
- stepper motor driver
- barrel jack power input
- Hall sensor module

PROJECT REQUIREMENTS

1. CONTROL / DISPLAY HOUSING

Design a two-piece enclosure consisting of:

- upper/main shell
- removable lower access panel secured with screws

The enclosure will contain the electronics and wiring and should include:

- mounting standoffs for circuit boards
- front cutouts for display, dial, and buttons
- rear access opening
- basic internal wire management features
- clean, serviceable layout

The housing will also include slotted mounting features that interface with matching slots on the motorized assembly using T-bolt style connectors.

2. LOWER MOTOR UNIT REFINEMENT
Refine the existing motor housing design and add:

- removable screw-fastened access panel
- improved wire exit provisions
- quick-turn locking top feature (bayonet/twist-lock style preferred)

3. REMOVABLE INNER CUP / LINER
Add a removable cup-style insert inside the existing motorized assembly.

This insert should function similarly to a removable blender or food processor insert and include:
- inner wall structure
- floor surface
- aligned opening matching the existing chute location

IMPORTANT NOTES

- Existing Fusion 360 files already exist
- Existing parameter naming conventions should continue where practical
- Preference is for organized parametric construction wherever practical
- Main existing structure is already completed and functional

I WILL PROVIDE

- current Fusion 360 files
- dimensions for housings
- dimensions for circuit boards and components

Please include relevant enclosure/mechanical design experience
