Dodecagonal Prism & Star Prism
 
 | The Dodecagonal Prism and Star Prism are build from three Square-1 or Cube 21. I Used 3
Cube 21 Sliver Edition. |
| First you need to disassemble three Cube 21 |
 
| Remove all center caps with a sharp Scalpel knife. |
 
| One one side you will see a screw, turn it lose, this puzzle will split in two. |
| You can make the rough prism like this: |
| Dissamble the three cubes. Select all coner parts for the Dodecagonal Prism. And sellect
all middle parts for the Star Prism |
| First make the Star Prism. Select the corners, cut down the middle part. let the
corner overhang like this: |
 
| No cut down the corner, do not cut exact on the mark, leave some room for corrections.
You can not add! So saw the piece so that you can sand it to fit. |
| Remove the cap |
| Cut down a bit, you can also sand it to fit using sandpaper 60 |
| Make the middel part and cut the center cap. Please *note*
that one edge on the cap is not a straight cut! |
| You can fill caps using the solder Iron method. |
 
| Before glue the parts, sand down the pieces until they fit, you can use the other
corners as guide. |
| The new center part, now clue the parts *Warning* Do not glue the center parts piece where the screw is located! You must
glue this piece as last! |
| It fits! |
| The next center part, build this until the last piece under the screw, You might need to
fill the other center part with soem milliput. This since the screw must fit tight.
Sticker all pieces, assemble the centerpart and glue the last piece. Done! |
| Now make the Dodecagonal Prism. Select the edges, cut down the middle part. let
the edges overhang like this: |
| Now cut down the center part, each segment is 13.5 mm. |
 
| Make from the center caps (they are 14mm width), 10 segements size 14 mm x 13.5
mm. |
| Sand with sand paper 1200 the edges so that they are a bit round, *WARNING* Do not glue the segments
on the halve where the screw goes in. You can finish the other part. When placing the
segments sand to fitthe center part for each segment. I used
the solder Iron method to fill gaps, you will only see the edge of
the segments. So the part does not have to be perfect on the inside only the outside! |
 
| And apply the stickers! |
