This file prints a set of parts for making a simple automaton, or cranked machine. It is scaled for use with 1/4 inch (6.35 mm) dowel rods. It includes a crank with a knob, several cams, crankshaft arms, a pushrod connector, and some tight-fitting washers.
I created the parts with Tinkercad. I printed it on my Original Prusa i3 MK2.5 in PETG at .2mm layer heights, and it works well. I have not tried scaling it up for larger dowels, but I suspect it will work fine.
I don't know if my video will upload, but the parts can be seen in action out Youtube: https://youtu.be/e-Ed6KFVhrs
Explore the .pdf file for advice on how to use these parts.
These are all made with Tinkercad basic building blocks. I sliced it with Slic3r.
Overview and Background
This is a set of 3D printable parts for making quick and simple automata. It is up to the student what action they would like to animate. These parts, plus a 1/4" dowel and some cardboard are enough to get started. The pieces fit snuggly enough where appropriate that there is no need for glue in the mechanics.
Lesson Plan and Activity
This collection of parts will start any beginner into building machinery that performs any of a wide sort of actions. Automata can be used in animating reports, dioramas, for 3D interactive infographics, or practically anywhere one's imagination might lead.
1/4" dowel, cardboard, tape (at the simplest level) White glue or hot glue is a next step up.
- critical thinking
- problem solving
The instructor should practice using the kit beforehand.
