3D Print design needed - Go Pro Rear Pillion Pegs Mount

IProject Title:
Design a Heavy-Duty 3D Printable GoPro Mount for Motorcycle (Rear Footpeg Mount – M8 Bolts)

Project Description:

I need a custom 3D model designed for a heavy-duty GoPro mount that attaches to the rear footpeg mounting points on a motorcycle.

This mount will be 3D printed at 100% infill, so it must be designed to be structurally strong, rigid, and capable of being tightened securely with bolts.

Mounting Specifications:

Mounting location: Rear footpeg bolt holes

Bolt size: M8 x 45mm

Distance between bolt hole centres: 2.75 inches (69.85mm)

Must allow proper clearance for M8 bolts and washers

Holes should be accurately spaced and aligned

Design must allow bolts to be tightened firmly without cracking or deforming

GoPro Attachment:

Must include a standard GoPro 3-prong mounting interface (male type as shown in the image)

Compatible with standard GoPro thumbscrew

Should position the camera slightly outward and downward similar to the example image

Solid, non-flexing design

Clean, functional look (no branding or engraved writing required)

Structural Requirements:

Designed specifically for 100% infill printing (strength-focused)

Thick base plate around bolt holes

Reinforced arm between mounting plate and GoPro mount

Filleted internal corners to reduce stress points

No thin arms or weak sections

Suitable for PETG / ABS / Nylon printing

Designed to resist vibration at speed

Deliverables:

STL file ready for printing

STEP file or Fusion 360 file (preferred for future edits)

Accurate tolerances for M8 bolt clearance

GoPro mount dimensions matching OEM spec

Notes:

Strength and vibration resistance are top priority.

It must sit flush against the mounting surface.

I will likely print at 100% infill for maximum strength.

If you have experience designing structural motorcycle components or vibration-resistant mounts, please mention this in your proposal.
