PRESEASON / CAD + 3D PRINTING

FIRST 3D Parts
Design challenges.

Choose a useful part, build an original version in Onshape or Autodesk, and submit your work for coach review. These visual guides are Team 3171 study icons, not vendor models.

How it works

  1. Measure the real interface or use an approved practice mockup.
  2. Model your own design with editable dimensions.
  3. Submit CAD, export, print plan, and explanation in Academy.
  4. Wait for coach approval before any print or robot use.

Use official supplier documentation to research compatibility: AndyMark printable-part examples ↗, REV starter-bot build guide ↗, and WestCoast Products belt and pulley reference ↗.

Prototype shaft spacer

Model a parametric spacer for a practice shaft interface. Include a named bore parameter, outer diameter, width, chamfers, and a drawing. Measure a sample interface before choosing dimensions; do not assume a supplier standard.

What to submit
  1. Onshape or Autodesk native design link/file.
  2. STL or STEP export and a dimensioned drawing or screenshots.
  3. Material, orientation, and fit-test plan.
  4. What changed after your test or review.

Print and robot-use rule

Submitting a model does not authorize a print, a printer reservation, or robot installation. A coach reviews the fit, material, load, safety, service access, and current FRC rules before approval.
