Dodecahedron
thingiverse
Print 12 of these and assemble them into a Dodecahedron! there is a small ledge on the inside so you can cut out material (paper, acetate, etc.) to place on the inside of one or more of the pentagons to create a solid and/or transparent shape. You can also scale this up and down as you like, just print all your pieces at the same size. For the one in the pictures, I used my Cricut to draw the lines and cut out the pentagons from pink cardstock. If you want the Cricut files send me a DM here or from my site.
With this file you will be able to print Dodecahedron with your 3D printer. Click on the button and save the file on your computer to work, edit or customize your design. You can also find more 3D designs for printers on Dodecahedron.
