Universal VR Pool Cue Attachment Design -- 2

I need a mechanical designer to create a back-of-cue attachment that lets me drop any major VR controller into place and start shooting virtual pool. It must grip the cue with an adjustable clamp that tightens cleanly around shafts from standard 12 mm up to break-cue diameters; no straps or sleeves—just one reliable, tool-less clamp.

At the opposite end, I want another adjustable clamp with padded grips so I can swap between Meta Quest, PlayStation VR, and SteamVR controllers without worrying about scratches or slippage. The design should balance the overall cue length so the controller sits where a bumper normally would, preserving a realistic stroke.

Please build the model in CAD (Fusion 360, SolidWorks, or similar) and deliver:

• Fully detailed 3D files (STEP or IGES)
• Exploded assembly and dimensioned drawings ready for prototyping
• A brief bill of materials noting hardware, fasteners, and recommended padding

I’ll test fit on multiple cues and controllers; final approval comes when I can clamp, tighten by hand, and play a full rack without movement. If tweaks are needed, a revision or two is part of the job.
