A chicken shaped catapult cut from an A4 piece of 3mm acrylic or plywood. Developed by myself AJ Booker, for my client the Nottingham eLearning Centre www.nelc.net it is one of 8 FREE projects I designed and developed on the www.notadesktidy.org website I set up for them. Each includes 3D model files, a user manual, sample files, images, introductory films, worksheets and powerpoint presentations. The catapullet includes an extra presentation where I narrate the steos in designing and prototyping the catapullet
This file was exported from 2D Designer as a DXF file, a rather basic educational Cad Program. It is intended to be cut in 3mm acrylic or plywood. Depending on material you may have to fiddle with the settings. Make sure the rubber band is not too stromng and use M3 bolts to fasten it all together. I have also uploaded the teachers guide and presentation. I developed this for the Nottingham eLearning Centre as part of a suite of 8 FREE projects located at www.notadesktidy.org and all files are there for the taking.
