I started with a dodecahedron. I made the 3D printed vertex to be a sleeve for all the straws to "plug" into.
Then I realize that it would be faster to print and prettier too if I insert the straw into the vertex!
I found that multiplying the object in Fusion rather than in Cura creates a more efficient packing. I have 12 in the model then I multiplied it five times in Cura for a total of the needed 60 vertices. I think it took 8 hours to print on the Ender 3.
That'd be cool! The Truncated Icosahedron is made up of pentagons surrounded by hexagons. Angle between pentagon and hexagon are 142.62° Angle between hexagon are 138.189685° More info at wikipedia: https://en.wikipedia.org/wiki/Truncated_icosahedron Please let me know the link to the openscad version. when you got it working. Thanks!
Sure, I'll upload it to thingiverse tonight and add a link to it here. No guarantee how well the fit would work for everyone's printer. I suppose you could scale it until it fits snugly for your printer and straw.
With this figure I have just made a modern lamp for my son. Very interesting!
