It is time to bring the venerable mousetrap car races into the modern age with a 3D printed mousetrap car. This product contains the files necessary to print and assemble a Mousetrap Powered Car. The printed files uses CDs or DVDs for wheels. The car is so light it needs the wheels for weight. The wheel hubs are designed to fit snugly into a standard CD opening. A pencil can be used for the extended armature, and a strong thread or string can be used for the axle system. The license for this pro

These three printable models make assembling the popular Balsa wood mousetrap car kit a simple, repeatable, process. This download includes three files : Brass Axle Adapter - Fits over the Brass Axle supllied with most kits CD Wheel Lug - Allows the learner to easily install the CD onto the Axle Clips - Replaces the use of glues for easy assembly and repostioning

An LED ( Light Emitting Diode ) is an ubiquitous device and is very simple. It's operation can seem mysterious but can be understood by knowing the components. This diagram clearly labels each of the components and gives some simple memory aides for understanding.

This is a distance learning, google doc friendly way to have students design and build a Rube Goldberg device at home during the quarantine.  It is based on the new Bar of Soap Rube Goldberg Video Challenge recently released by rubegoldberg.com. The project is broken down into steps where students are required to complete a short journal entry every 2 days with their progress. The project also incorporates the skill of having students identify the energy transformations that occur with each step

A detailed diagram of the components of a basic Roller Bearing.

This Diagram shows an exploded view of a Momentary Push-button. This allows the learner to get an inside look at the push-button to aide in understanding of its functionality.

Learning CAD system requires items to model. The wll known 608zz Skate bearing is a great place to start. This PDF of the 608ZZ can be used alongside the diagram on this site to model an accurate representation of the bearng
