Geoboards are widely used in early math to help students make sense of geometric shapes and their algebraic properties such as the Pythagorean Theorem. They can be used for a variety of topics or just for fun. The geoboard files here are designed for K-12 teachers, with reinforced pins and hollow spaces underneath to reduce warping and for easy removal. Each pin has three positions to allow multiple layers of rubber band construction. There are three different dimensions and two styles. They are no larger than 140mm x 140mm x 32mm. I don’t see any point in making a 3 x 3 board. Large ones are certainly possible if necessary. There is an isometric (5x5) one for special needs; there is also a circular one for playing with angles and fractions. Everything is made using Autodesk Fusion 360™. You would need a bag of thin (and colorful, preferably) rubber bands to use the geoboards. Regarding printing, PLA is fine at 0.20mm, without no support or raft.
