Geoboard with detachable pins. Geoboards provide a rich array of mathematical explorations in grades K-8. In this design, the pins are detachable. Consequently, if a pin breaks during use, it can be easily replaced. This design also allows for multiple uses of the geoboard. For instance, one can print pins in various colors and utilize them to model triangular numbers (1, 3, 6, 10, ...) or odd numbers (1, 3, 5, 7, ...). Children can certainly discover other ways to engage with them! If the pins are printed along with the holder, you can remove them by pushing at the bottom. If a pin is difficult to remove, you can use a screwdriver to push from the top. Be cautious not to injure your fingers! Alternatively, the pins, holder, and tray can be printed separately for later assembly. For resolution, one between 0.1mm to 0.2mm appears to be sufficient. An infill of 5% to 50% can be used, depending on desired durability. For traditional sets of geoboards, please refer to https://www.thingiverse.com/thing:2515293
