 | This puzzle was build form a keychain Rubik's cube as kernel and I used 3x3x3 cubies for
the outside. The method is based on the method described on Tony
Fisher's Cuboid 3x3x3 Transformations. I optimized the building method; I do not need
to build special parts |
What is different:
| I used a keychain kernel and normal 3x3x3 Cubies for parts |
The kernel is a 3x3x3 keychain, one corner is glued to the two edges and a center. This
will make the 3x3x3 function as a 2x2x3. 8 edges are rounded to make it possible to turn,
these are the top and bottom internal edges. The other 4 edges of the keychain kernel are
used in the 2x2x3 Edge piece.
| The corners of this 2x2x3 is a 3x3x3 corner filled first with a bit of tempex and than
milliput, and fused with a 3x3x3 keychain corner. |
| The edge of this 2x2x3 is a 3x3x3 edge with some iternal plastic removed and fused with
a 3x3x3 keychain edge. |
 
| Use some super glue to glue one corner to the two adjacent edges and the center. |
| To round the edges you can use a dremel precision drill with a grind stone to sand down
to a round shape. |
| To make the curve in the corners, you can use a Dremel grind stone 8215. |
| Remove the plastic of the edges using a dremel 932 grind stone, you can use a Dremel
grind stone 8215 to make the curve |
| You should fill all corner with the milliput at the same time and push the corner cubie
on the a corner of the kernel. Optional you can use some tempex (used in packing material)
to make the piece a bit lighter. Before the milliput dry do some test turns and remove
milliput that purged out. After this put all pieces in place you can use tape to hold and
put the pieces in the correct positions. The edge pieces will be put in place and
not filled with milliput. This can be done after the corners are dry. |
| Fill three edge with milliput and push it on a mini edge in krenel. Remove the piece and
remove purged put milliput, put is back in place and use tape to hold and put the pieces
in the correct positions |
| Make the last edge after the three edges are dry |
| The 2x2x3 compared to a 3x3x3 |
