Simple Circuits TechCard Plus combines all the design and structural features of TechCard. With the added bonus of being able to build models quickly without the need for gluing. New, repositionable plastic rivets can make building extremely fast and act as pivots. TechCard Plus also introduces many new components including tyres, steering, axle plugs, safety propellers and contact springs all to help extend the building possibilities. All our kits are Curriculum focused and contain teacher’s notes. TechCard is pre-cut and scored and is easily formed into accurate and strong three dimensional components. Once folded the Techcard components are simple to fit together using the TechCard rivets. The TechCard beams, girders and bases are easily modified to create and infinite range of structural components. Adding dowel axles and card wheels creates a simple rolling chassis from a TechCard base.
