Swap the parts
Use off-the-shelf arms, clamps, adapters, and hubs so the kit can evolve fast.
Prototype Goal
Do not optimize for perfection. Optimize for discovery.
The first real prototype should discover geometry, posture, transitions, and what feels good physically. Subscribers get early hardware; 3DVR gets real field notes.
Hold it for real
Grip thickness, wrist angle, and texture matter more than a perfect CAD render.
Test daily positions
Couch, train, bed, desk, and cafe table use should all inform the final geometry.
Leave room to type
The handle should grow toward split keyboard wings and a tiny cyberdeck workflow.
Recommended V0 Stack
Easy to order. Easy to modify.
This stack uses existing parts to test the real invention: geometry, posture, transitions, and physical feel.

Kit Layers
What each part proves.
Tripod / extender core
Tests joystick mode, table mode, extendable viewing, and pocketable base assumptions.
Split typing layer
Tests lap mode, posture, and whether Nomad Clip can become a tiny cyberdeck.
Adjustable screen geometry
Tests neck angle, screen distance, lap balance, and ergonomic positioning.
Extra modular arms
Become keyboard wings, accessory mounts, cable anchors, and future AR support points.
Material feel
Cork, tennis grip, silicone, leather, or linen wrap determine fatigue, comfort, and perceived quality.
USB-C workstation hub
Turns the phone into an editing station, streaming setup, wired audio path, and mini desktop.
Subscriber Field Test
Give hardware to testers, not random people.
Frame this as a limited subscriber field test. The kit is not a free prize; it is a prototype exchange. Testers get early hardware and 3DVR gets honest notes.
- Who gets it: subscribers who will test lap, table, travel, and handheld modes.
- What they return: photos, comfort notes, posture notes, failure points, and one-minute videos.
- What they earn: early access, field tester credit, and possible discount on final hardware.
- What 3DVR learns: geometry, transitions, what feels good, and whether this should become real hardware.
Budget
Use the $300-700 as a small lab.
Two serious kits or a few lighter kits are better than spreading the money across weak parts.
