A low-profile rotating scan table built from one central hub, three detachable arms, and a choice of two top plates. Each arm carries one 608 bearing secured by a press-fit pin, plus a fourth bearing nests under the top plate. Choose between a top plate with built-in marker posts or a smooth version for your own fiducials.

Key Features

• Modular assembly: central hub, three arms, base, and two top-plate variants
• Four 608 bearings (8 × 22 × 7 mm): three in arms, one under the top plate
• Press-fit pins lock bearings into the arms
• Two top-plate options:
  • Version A: with integrated tracking markers for reality capture(AMS REQUIRED)(0.4mm nozzle works but 0.2 maybe better)
  • Version B: smooth surface for custom-applied markers
• Base supports wobble-free rotation of the top plate
• The opposing markers are 15cm apart so they can be used to scale the model in RealityCapture by defining the distances

Assembly Instructions

1. Print parts(Matte filament recommended):
   • arm.stl (×3)
   • base.stl
   • One top-plate variant:
     • top_plate_marked.stl for built-in posts
     • top_plate_plain.stl for a smooth surface
2. For each arm:
   • Press a 608 bearing into the circular cavity.
   • Insert the provided pin through the retaining holes to lock the bearing.

3. Snap the three arms into the central hub until they are equal height. It should be a friction fit but you can secure the arms with some CA glue to be safe.

   

4. Press the fourth 608 bearing into the bottom pocket of your chosen top plate.

   

5. Place the top plate (bearing-side down) onto the assembled hub and arms, resting on the base.
6. Verify smooth, wobble-free rotation by hand.
