PLA-Tonix is a series of 3D printed Platonic solids that use hinges to open up and show cross sectional geometry.
These octahedrons use internal hinges to display two different cross sections. The "square" model displays two square cross sections, while the "hex" model displays a square and a hexagon. The pictured models were both printed in PLA.
Additionally, the hex model prints with two small tabs to keep its cross section anchored while printing. Be sure to snip these tabs before you try to snap the hinges. I've included reference images of where the tabs are located to make the process of finding them a little easier.
I've included the gcode toolpath for the Prusa Mini+ and Ender 3 for those who just want to plug and play. Sliced with PrusaSlicer, but Cura will also work.
Print the square octahedron with its hinges on the build plate. This will eliminate the need for supports without decreasing print quality.
As for the hexagonal octahedron, printing it in its default orientation is fine.
Scale down solids to 65% once imported into the slicer.
