Mechanical design for custom automated chess board CoreXY base (3D printable, assembly-ready) Ended

I am developing a custom automated chess board with an internal CoreXY mechanism that moves a magnetic carriage under the board.

I already have the overall concept, dimensions, key components, and intended layout defined. I know how I want the system to work. What I need now is an experienced mechanical engineer / product design engineer to turn this into a fully resolved mechanical design that I can 3D print, assemble, and use.

This is not an early conceptual design project.
The concept already exists. I need someone to create the final mechanical base and mounting structure so the system can be built properly and reliably.

Scope of work

The project is to design the internal mechanical base of the automated chess board, including the mounting and integration of the CoreXY system.

The design must include:

1. Main structural base

A 3D-printable structural base that allows accurate mounting and alignment of the CoreXY system and its components.

This includes mounting and support for elements such as:
• stepper motors
• linear rails / guides
• pulleys
• belts
• carriage support
• structural reinforcement features
• mounting areas for related components if needed

The result must be a design that is realistically buildable, not just visually modeled.

2. Assembly-ready mounting design

The mechanical design must be fully thought through for real assembly and real use, including:
• screw locations
• interfaces between parts
• alignment features
• assembly logic
• tolerances appropriate for 3D printed parts
• rigidity and stability considerations

I do not want only a rough CAD concept.
I need a design that is ready to manufacture by 3D printing and ready to assemble properly.

3. Homing system with 2 endstop switches

The design must include an integrated homing solution using 2 mechanical endstop switches.

This includes:
• switch mounting positions
• trigger/actuator features that activate the switches
• proper placement for repeatable and reliable homing
• integration into the main design

This homing area must be fully resolved as part of the final mechanical design.

4. Final design ready to print and build

The goal is to end with a design that allows me to:
• print the parts
• source the required hardware
• assemble the full system
• install the switches
• align the mechanism correctly
• and have the internal mechanical system ready for use

Important requirements

This is a compact precision electromechanical product, so the design must prioritize:
• rigidity
• clean mechanical layout
• practical assembly
• repeatability
• realistic tolerances for printed parts
• good access to mounting points
• integration of homing
• suitability for repeated use

Precision is important because the movement must be reliable and repeatable.

Deliverables

Please provide:
• full 3D CAD design
• source CAD files
• STL files for printing
• complete mechanical layout of the base and mounting system
• endstop switch mounts and trigger design
• hardware/screw recommendations
• exploded view or basic assembly guidance
• notes about tolerances or print considerations if needed read less
