Pentakis Dodecahedron

This Pentakis Dodecahedron model is optimized for printing on an SLA/resin machine like the Form2. It's delicate and pushes the limit of what you can 3D print on a resin printer; in particular, you'll have to have steady and gentle hands to remove the support material without breaking the model. If you want a sturdier model, scale it up to a larger size before printing. To print on an FDM/filament printer like an Ultimaker, double the size of the resin model or download our previous [thicker version](https://www.thingiverse.com/thing:282534). Fun Facts about the [Pentakis Dodecahedron](https://en.wikipedia.org/wiki/Pentakis_dodecahedron): -Has 60 faces, 90 edges, and 32 vertices -Each of its faces is the same isosceles triangle -One of the 13 [Catalan solids](https://en.wikipedia.org/wiki/Catalan_solid) -Dual of the [Truncated Icosahedron](https://en.wikipedia.org/wiki/Truncated_icosahedron) -It's a [Dodecahedron](http://en.wikipedia.org/wiki/Dodecahedron) with five-sided pyramids added to each face -If you make the pyramids a little taller, then pairs of triangles combine to make rhombuses and you get another Catalan solid, the [Rhombic Triacontahedron](https://en.wikipedia.org/wiki/Rhombic_triacontahedron) (!)
