Practice: Flat Intake
A live-axle compliant-wheel intake on tube and plate, belt-reduced — and tube plugs instead of gussets.
01
Flat Intake
Model a flat game-piece intake: two compliant wheels, belt reduction, tube-plug mounts.
- Live-axle: the motor spins the shaft, the wheels ride the shaft.
- Bottom tube 1x1, top tube 2x1; 2 in compliant wheels.
- Tube plugs connect tubes without gussets.

Key Specs
Geometry
- Wheels 2 in; bearing offset 1/16 in
- Shaft start offset 9/32 in
- Motor bolt circle 2 in (8 holes, use 3)
Parts (FRC-COTS)
- 2x1 tube plugs (1/16 in sleeve)
- Hex bearings, hex spacers (1 in, 1/2 in)
- 2 in compliant wheels, shaft-end screws
02
Build It
Layout sketch, tubes, belt, then assemble.
- Tubify the tube profiles; use To-Object extrudes for parametric width.
- Belt reduction via AltSkripts Belt Generator; shaft via Shaft Endings.
- Mirror the second side.

Think About It
Push the parametrics.
Change the width, length, wheel positions, and gear ratio. Which edits update cleanly, and which throw rebuild errors? That tells you where your design intent is solid.
