This is my first Instructable, and my first entry into a competition! If you like this instructable, please vote for it in the Instructables Puzzle Competition, thanks!

I designed this puzzle a few months ago in Solidworks. While it was my own independent idea and design, I later learned that this puzzle has been made before, under the name of the "Rhombiminx", so I'll give a little bit of history about it before I go into how to make one.

From the TwistyPuzzles Museum:

"The Rhombiminx was originally built in 2003 by Laurent Blanc from a modified giant Rubik's 2x2x2. In 2008, it was independently designed and built by Garrett Ong using a modified Eastsheen 4x4x4 mechanism and cast tips parts made from handbuilt masters. Later on a second version was built using FDM printed master parts for a more precise build. In April 2009 a mini version was built using a mini Eastsheen 2x2x2 core and molding/casting. From the solving point of view the puzzles behaves like a 4x4x4 which contains just face cubies. The version from 2008 sold for 205 USD."

As far as I know, this is the first Rhombiminx that (besides the mini 2x2 core) has been completely FDM 3D-Printed. In this Instructable, you will learn how to prepare, print, assemble, and sticker a rhombiminx of your very own!

Step 1: What You Will Need


  1. FDM 3D Printer (I used a printrbot simple meta, but any model printer should do)
  2. Hot Glue Gun


  1. PLA 3D Printer Filament
  2. Hot Glue
  3. 3x3x3 Rubik's Cube Stickers
  4. Xacto Hobby Knife (or scissors)
  5. Eastsheen mini keychain 2x2x2

.STL Files

  1. Print 8 copies of Rhombiminx_Filleted_1.stl
  2. Print 24 copies of Rhombiminx_Filleted_3.stl
<p>That is very disorienting. I like it.</p>
<p>Thanks! I suppose that is the key to making a difficult twisty puzzle.</p>
<p>Awesome puzzles. You should enter it in the Puzzles contest that is currently running.</p>
<p>Thank you, and I just have! </p>
