Draw a circle which is a little bit bigger than your candle. My candle was about 60mm in diameter, so a 70mm circle was good. Now draw a hexagon, which is bigger than the circle – I would choose about 10mm in each direction.

Center this hexagon and the circle.

Now add a rectangle of 4mm x 4mm in one corner of the hexagon, but still in the middle of the material. (see image). This hole will take the spacer later.

We need this hole in three corners of the hexagon. So select the hexagon and the rectangle, group both and use the Array->Circular Array function to make two more copies, each rotated by 120°.

Now we have three holes at the correct position, but three hexagons at the same position. This would result in a multiple cut of the hexagon later. So select the top hexagon, choose ungroup, unselect everything, select the hexagon and remove it. Repeat this one more time.

The result is one hexagon with 3 holes. These are the holes for the spacers that go up to the next hexagon. We still need spacers that go down to the hexagon below. And we have to keep in mind that we want this hexagon to be turned slightly against the lower one.

So select the hexagon and the three holes. Group this and use the Array->Circular Array function to create a copy which is turned by 55°. Select the hexagon, ungroup, unselect, select the hexagon again and remove it again to get rid of the additional hexagon.

We now have constructed our basic geometry.

Make a copy of the basic geometry. Remove the circle and remove the hole that you have added with the 55° rotation. This is you bottom part.

Make a second copy and just remove the three holes that were created first. This is your top part.

I decided to have my hexagons about 4mm away from each other. I wanted spacers that form a + 4mm by 4mm in the lower and upper part and a middle which is slightly wider – 6mm by 4mm. I constructed this from individual rectangles and used the Combine->Unite function to join the rectangles to my cross-shaped spacer.

In the provided design I have also added spacers with a slightly different design. Choose what you like.

We will need three spacers per level.

On the S1 it took about 15 minutes to build all components.

Glue three spacers in the holes of the bottom piece. Now glue the first middle piece to it, but in a way that it is turned by 5 degree. Glue spacers in the remaining holes and glue the next middle piece again turned by 5 degree. Continue this until you have reached the top part.
