How this is scored
Five stages of the engineering design process, then the model itself. Everything here is scored at your presentation, so show all of it there.
All individual
This is a solo project. Every score on this page is yours alone — your movement, your model, your record.
Your daily work — safety, cleanup, effort, organization — isn't scored here at all. That lives in the daily standards.
Define the Problem
Do you understand your movement, and what the museum needs from it?
Names the movement by number. States the input and output motion, identifies the frame, and explains the one detail that makes the movement work. Names which requirement is hardest for this particular movement — survives handling, runs without sticking, or repairable — and why.
Describes what the movement does, but not how. Input and output are named but the key detail is missing. Requirements are repeated from the brief rather than weighed.
The movement is described vaguely or incorrectly. Can't say what goes in and what comes out.
Research and Brainstorm
Did you research it properly, and sketch it before you modeled it?
The research report answers all five questions, with sources. A detailed hand sketch with real dimensions on every critical feature, drawn before the CAD model. Printability problems are identified in advance, each with a proposed solution — some of them creative.
Good research, but one or two questions answered thinly. A clear sketch, but some critical dimensions missing. Problems are listed with basic solutions.
Minimal research. The sketch is incomplete, undimensioned, or drawn after the model was already built.
Prototype
Is the Onshape model ready to print, and designed for the printer?
A professional Onshape model attached to the 507 Movements assignment. Every part modeled and assembled with correct mates. Clearances designed in on purpose, print orientation planned, overhangs and supports minimized, hardware mounting points included where needed. Parts carry version numbers, and the STL files are ready to print.
A functional model with minor issues — a missing mate, a clearance guessed rather than tested, or parts that need heavy supports. Tolerances are mostly appropriate.
A basic model with significant design problems. No clearances, parts that can't be printed as drawn, or no assembly.
Iterate
Did you document every print, and change things for a reason?
A comprehensive record of every prototype: photos, specific problems, a stated cause, the change made with numbers, print settings, and assembly notes. Each change can be traced to a new version number in Onshape. Includes at least one change that didn't work and what it taught you.
Good documentation of the major iterations, but some changes lack a reason or numbers, or print settings are missing. Only successful changes reported.
Little evidence of iteration. A photo of the final model and not much else, or changes made with no record.
Communicate
The 5-minute presentation.
Shows the Onshape assembly animating. Walks through the design problems and how each was solved, justifying at least one decision with a specific number or principle from class. Shares a real lesson learned. Answers a follow-up question clearly. Fits in five minutes.
Shows the model and describes the process, but justifications are general — "it fit better." No animation, or lessons learned are vague. Runs well over or under time.
Reports what happened without explaining why. Missing major parts of the presentation.
What "a specific number or principle" sounds like
This is the line between a 3 and a 5 on Communicate, so here it is out loud.
A 3: "The gear kept getting stuck, so I made the hole bigger and it worked."
A 5: "My gear bound on its axle every turn at the same spot — that was the z-seam bump. I moved the seam in the slicer and raised my clearance from 0.2 to 0.3 mm, which is version 3. It spins freely now, and it still doesn't wobble out of mesh."
The model is scored too
Separate from the five stages, the final model gets its own score when classmates handle it at your presentation.
Runs Smooth
Can a classmate pick it up and run it?
Fully functional. Runs through repeated full cycles in a classmate's hands without sticking, and does what Brown's drawing does. Professional assembly — nothing loose, no glue blobs, no support scars on moving faces.
A working movement with minor issues — a sticky spot, a part that needs holding in place, or rough assembly.
Limited functionality or poor assembly. Only works when you run it, or only for part of a cycle.
