  1. Thank you for sharing! 😀 The shapes and colors are beautiful! I want to get some! I hope you are letting your children play wuthering them!

  4. I have constructed snub dodecahedra and posted them on Facebook at the Magformers UK page and one other Magformers page. I have also made decagons and have constructed and posted pictures of ALL the Archimedean solids. I think you and I are alike. I found a site that sells octagons, and I bought them, but that site seems to have gone away. Magformers later sent me six more octagons. But I have found another site that sells them if you want more! I have 15 decagons and am building at least 9 more so that I can construct all Archimedean solids simultaneously. I’ve also constructed many Johnson solids and some space tessellations and various Stewart toroids. I’ve compiled a list of possible builds of solids within solids—e.g. solids with various internal structures. I’d be happy to trade pics and other ideas with you, and my decagon construction technique. It’s labor-intensive but I have some ideas for making it easier.

  5. One minor mistake: The two semi-regular tilings (tessellations) that you can’t make with Magformers are those requiring dodecagons, not decagons. Of course, you know that there are no 2D tilings with decagons. Great blog. I haven’t read it all yet, but will enjoy doing so! Thanks!

      • Now THAT would be an insane project. Alas, no; the only payoff would be to build those last two uniform 2D tilings. Well, they would look pretty cool, too. But for now, there’s just not enough incentive for that massive undertaking. Some time in the future, if I can find an easy way to mold or 3D print them, then I’ll put dodecagons on the project list!

      • You probably know that you can create your own dodecagon using 1 hexagon, 6 triangles, and 6 squares. If you have enough of those shapes with the same color, you can make some nice 2D tilings with dodecagons. You may recall that you “liked” a Facebook post of mine featuring 12.12.3 dodecagonal tiling on Sep. 28, 2019.

  6. Awesome post! I also immediately started constructing the Platonic solids when my kids were given a set of magformers. Then I moved on to the Archimedian solids. I haven’t been able to track down any octagons here in the U.S. (there’s a small set that includes one but they’re out of stock everywhere I can find them listed currently), and I found this post trying to learn if they make decagons. It appears they don’t, but thanks for pointing me to the Johnson solids and space-filling possibilities – now I have more projects to work on until I can get my hands on some octagons.

    I finally acquired enough triangles recently to make a snub dodecahedron, with the help of my six-year-old, but it was of course very unstable. It was very satisfying to have made it, though.

    • Thanks! Alas they don’t make decagons. (Although Michael [see comments above] has managed to create his own.) You and he are convincing me that I’m going to have to invest in more triangles and have a go at the snub dodecahedron!

    • Laura, try this site for octagons: http://www.apluscompass.com/magformer_shapes.htm. Unfortunately, the site where I got my first six octagons, U-I School Supply, disappeared about a year ago. I’ve found the snub dodecahedron stable enough to carry (carefully). If you find my Facebook page, you will see many pictures of my creations, including the two Archimedean solids that require decagons. I’ve also posted pictures on the UK and US Magformers Facebook pages.
