25 Years of MAE 3
Spring 2025 Contest Table
This is an f3d file containing a complete CAD model of the contest table for this quarter's robot contest
MAE 3 CAD RULES
Students must generate all CAD used for their robot, 3D printing and laser cutting except for the items on this website
Gears Tempates
These zip files contain pre-drawn gear files for various pitch sizes. The most common gear sizes for MAE 3 are 10, 12 and 16 pitch gears
DWG Download (upload into Fusion 360 - dimensions are in mm)
DXF Download (upload into AutoCAD - dimensions are unitless)
Note: You will need to give extra room between the pitch diameters. If you align the pitch diameters to be perfectly tangent, it will cause interference issues in the teeth. You can and should rotate and move the gears to check proper placements
Gear generator
If you need a gear size that isn't on the template above, you can use this Gear generator
The pitch module is a ratio between teeth number and pitch diameter, so for a gear with a diameter D and tooth number N, you'd want to use a module D/N.
Be mindful of units since this site makes gear with millimeter dimensions.
large gear teeth are stronger, and are less likely to skip. However for a small gear dimension you need smaller gear teeth since the minimum number of teeth in a gear is about 12.
Timing Belt Pulleys
These files contain various pulleys (AKA sprockets) for use with the robot kit timing belts
DWG Download (upload into Fusion 360 - dimensions are in mm)
DXF Download (upload into AutoCAD - dimensions are unitless)
If the templates above are not working, or if you would like a more specific size please visit this online timing pulley generator. Make sure to set the pulley size to XL, then specify the amount of teeth you would like on the pulley.
Gear Racks
These files contain all the rack templates for every gear set

Large, High Speed Motor (Non-Geared)
This is an f3d file that can be downloaded and uploaded to Fusion 360
Large, High Speed Motor Mount template
This file contains the template for mounting this motor
Geared Motor [1]
This file contains a parts file model of this motor and can be opened in Fusion 360
Geared Motor [2]
This file contains a parts file model of this motor and can be opened in Fusion 360
Geared Motor Mount Template
This file contains motor hole mounts for mounting on the shaft of the geared motors
Note: NEVER press fit onto a motor shaft. This template is good for Lasercamm-ing. 3D printers usually print holes slightly small, so sizes will need to be adjusted
Drawing Template
Use this template for your Fusion 360 CAD assignments in the robot project
