Tweaked meirm's Stackable Polygons to:1) Make the OpenSCAD code more parametric and commented (i.e. replaced numbers with variables and equations). 2) Made the ends of the 'bones' rounded, to make them easier to slide onto the 'polygons'.Meirm did the hard math, and the polygons were already parametric (number of slots).Attached are STL files for polygons with 6 and 8 slots, and 'bones' length 20 mm and 40 mm.Print a bunch, build stuff.If you want different numbers of slots in the polygons, edit the OpenSCAD script and change nrslot (parameter at the bottom of the script) to any number between 3 and 12, and generate your own.Similarly, if you want 'bones' of different lengths, change 'bonelen'.Have fun! And thans, meirm, for such a cool thing to print.
