Modular frames for instructional use that provide secure mounts for geometric solids are presented. Some contemplated modular frames can be assembled into three dimensional modular devices and are particularly suitable for instructional purposes. Modular devices comprising two or more frames could be coupled via a clip in two or more different configurations. Containers including conductive material and configured to provide a Faraday cage around their contents are also provided. |
