Stella Octangula Plant Pot

Creating a Stella octangular plant pot from plaster

you will need a piece of paper, a pencil, a set square, and a compass as your materials

Draw a 22.5 cm straight line from the right edge and at the bottom of the A4 paper and draw points on the line every 7.5 cm.

Taking the compass and the set square place the needlepoint on 0 cm and drag the pencil part out to 7.5 cm

Take the needlepoint of the compass and place it on the right corner of the line and draw a curve to the left.

Then move the needlepoint to the next point on the line and draw a curved line to the right creating a cross

Repeat this with the other points on the line

Put your pencil on the first point and place your set square against it and through the cross.

Now draw a line creating the first side to your triangle.

Repeat this with each point and cross on each side of it.

Take the set square a place it next to the top of all triangles and draw a line to connect all of them together from the right edge of the paper.

Extend the line to the left by 7.5 cm and connect that corner with a straight line to the left corner of the bottom line making one more traingle.

Use the tips of these triangles as the new points and repeat these steps until you get 16 triangles.

You will need a sheet of high impact polystyrene, glue, scissors, and the piece of paper with the drawn triangles.

Apply glue to your A4 paper with the drawn triangles and glue it next to the edge on the matte side of the high impact polystyrene

Take your scissors and cut out each triangle having straight lines. Peel off the paper and put the triangles to the side.

You will need a new A4 paper, a set square, a pencil, and a compass.

Draw a 20 cm straight line from the left edge and at the bottom of the A4 paper and draw points on the line every 10 cm

Taking the compass and the set square again, place the needlepoint on 0 cm and drag the pencil part out to 10 cm

Take the needlepoint of the compass and place it on the right corner of the line and draw a curve to the left.

Then move the needlepoint to the next point on the line and draw a curved line to the right creating a cross

Repeat this with the other points on the line

Put your pencil on the first point and place your set square against it and through the cross.

Now draw a line creating the first side to your triangle.

Repeat this with each point and cross on each side of it.

Take the set square a place it next to the top of all triangles and draw a line to connect them together from the left edge of the paper.

Extend the line to the left by 10 cm and connect that corner with a straight line to the left corner of the bottom line making one more triangle.

You should now end up with 4 triangles

Again you will need a sheet of high-impact polystyrene, glue, scissors, and the piece of paper with the drawn triangles.

Apply glue to your A4 paper with the drawn triangles and glue it next to the edge on the matte side of the high impact polystyrene

Take your scissors and cut out each triangle having straight lines. Peel off the paper and put the 4 triangles to the side.

You will now need your 16 mold high-impact polystyrene triangles and some sellotape

Take 4 triangles and place them like this with the glossy side up. Tape each edge securely making sure no tape gets on the matte side

Now take 6 more triangles and tape each one tightly to the edge of one of the triangles from the base. Make sure you are taping the glossy side. It should like this.

Take 6 more triangles and tape each one to the inside edge of the corner triangle. You will end up having 2 side triangles between the corner triangles. It should look like this. Make sure the tape is well sealed on the glossy side.

Take 2 side triangles and place the edges together and tape it securely making sure the glossy side is on the outside. Seal the rest of the edges together so there are no leakages

Repeat this with the other 4 side triangles

It should end up looking like this.

Flip your mold around and take a pair of corner triangles and tape the edges together. Seal the edges carefully only placing the tape on the glossy side. Repeat this with the other 4 corner triangles.

The ending product should look like this with the big opening.

Tape all the corners on the outside and make sure every single edge corner is sealed while having no tape on the inside. Set this aside

You will now need the 4 core triangles and some sellotape

Take all 4 triangles and place them face-up on the glossy side like this. Tape all the edges together tightly, making sure there are no bumps.

Take any two side triangles and tape the edges together sealing them tightly. Make sure the tap is flattened down. It should look like this

Take the third triangle and tape the edges to the other two triangles sealing the core. Make sure the tape is all flattened down and the corners and sides are well covered with tape.

You should end up with a triangular pyramid shape like this

Now you will need a bucket, a spatula, two yogurt cups, tap water, plaster powder, sellotape, your mold, and your core.

Add two yogurt cups of water into the bucket and then add two cups of plaster powder. You can increase the amount slowly to get the right consistency.

Working with speed fill three-fourths of your mold with plaster and place your core in the center pushing it all the way down. Tape the core so it stays stable while the plaster dries.

Tape any corners or edges that have leaked and set your mold aside for 3 days to dry,

After 3 days you are ready to open your mold. You will need an Exacto knife. Slice open the edges of the corner and side triangles and squeeze the core out of the plaster.

File down the top/opening if there are any bumps. Drill a hole in the middle of the base and then your plant pot is complete.
