Custom Manufacturing Project - Bicycle Handle Grip Example
Tips:
Make sure your modeling clay object is smooth and well finished. The scanner is very accurate and will pick up on minor details.
If Onshape is running very slowly once you have imported your scan make sure you simplified your model in the 3D scanner software. This reduces the number of triangle faces on the .stl file from ~300,000 to ~20,000, which the computer is much more capable of handling.
Project Instructions
Overview:
Recently the Cambridge Design Partnerships created a steering wheel the Bloodhound supersonic car custom fitted to the driver’s hands. Using the 3D scanner and modeling clay you will create a custom grip for a device of your choice.
Problem Statement:
Using the Sol 3D scanner you will create an object with custom grip fitted for your own hands and 3D print them.
Problem Description:
You must an 3D print object you could use that would benefit from a custom grip. Using modeling clay create an imprint of your grip, scan and import it into Onshape, modify it into an ergonomic piece, and 3D print it. The example given is handlebars, but other ideas include video game controllers, computer mouse, or other ideas you may have. If the object is not a bicycle handle please run it by the teacher before going further to make sure the idea is appropriate.
Requirements:
Final product must be molded to the shape of your hands
Must use 3D printers to create your final product
Final product is neat and lacks rough edges
Material:
Modeling clay
PLA
Includes instructions on how to use the SOL 3D Scanner, simplify and upload your scan, and align the design once imported into Onshape.
