I am now offering my Mechanical Mini Pentultimate as a DIY kit for $99/€85 on Shapeways.
Thanks to it's extraordinarily small size of 25mm on an edge, it is very inexpensive. This puzzle uses a shells mechanism, which builds up from a Megaminx through a Pyraminx Crystal to a Master Pentultimate. It turns very smoothly and is exceptionally stable. Though the parts are intricate and delicate, the puzzle as a whole is very sturdy and is not at risk of breaking at all (under reasonable use, at least).
Vist my custom puzzle shop
to buy your very own Mini Pentultimate DIY kit for just $99/€85 (free UPS worldwide shipping).
Due to high demand, I have to charge $200+shipping for the assembled puzzles. Please consider assembling the puzzle yourself (it's a lot of fun! But not when you have to do it seven times...) or even seeing if you can pay another forum member to do it for you.
PS: I'm looking forward to being able to write the alliteration of Mechanical Master Mini Pentultimate
