Two-Axis Gimbal for Optical Terminal

I need a two-axis gimbal designed for an Optical Communication Terminal (OCT). The gimbal must have mechanical stops at extreme ends, a mass of less than 6kg, and zero backlash.

OCT Specs:
- Size: 120x100x100 mm
- Mass: 2 kg (uniform distribution)
- Mounting: 6x M3 tapped holes on bottom face

Gimbal Specs:
- Field of regard: ±110° Azimuth, ±45° Elevation
- Mechanical stops at extremes
- M5 mounting provisions on base
- Use commercial off-the-shelf BLDC motors and bearings

Key Deliverables:
- STEP file of the full unit
- Engineering drawing of one part
- Bill of Materials (BOM)
- Torque calculation for motor selection (1 deg/s²)
- Center of Gravity (CG) position

Ideal Skills and Experience:
- Mechanical design
- Gimbal stabilization systems
- Experience with BLDC motors and bearings
- Torque and CG calculations

Looking forward to your bids!
