The cultural artefact I created using the tinkered software is a 2000-year-old sapphire ring that once belonged to Caligula, also known as the third Tyrannical ancient Roman emperor during the Roman Iron Age. The ring is mainly made of sapphire and a portrait of Caligula's fourth wife, Caesonia is curved on the surface of the ring.

The software I used to create the model of my cultural artefact to 3d print is called 'Tinkercad'. Other supplies I used throughout the process of creating / designing my artefact would be a paper and pencil for sketching and a laptop to use the tinkered software.

I used one tube shape to first create the gold inner part of the ring. I also used another tube shaped figure to create the outer part of the ring and changed the colour to a light bluish colour to represent the sapphire part of the ring. I made sure the inner gold ring perfectly matches the outer part of the ring so that there won't be a tiny gap between the two parts.

The wall thickness for the inner gold part is set to 2.3 with 64 sides which is the maximum amount of sides so it will look as smooth as possible. For the blue outer part of the ring, the wall thickness is set to 2.3 and I added a bevel of 2.3 to make it look as similar as possible to the original artefact.

Next, I created the top surface octagon shaped part of the ring. I tried using shapes such as diamond and icosahedron to see which would fit better but I ended up using the polygon shape to create an octagon shaped surface. I changed the number of sides to 8 and elongated the shape to match the shape of the ring. I made a copy of the whole ring and paste it in the corner just in case so if I made a mistake, it would be easier to go back. Throughout the making process, I made sure to look at the picture of the original artefact because it can help me to make my design look as similar as possible to the original ring.

While looking at the picture of the original artefact a couple of times, I realised that the top surface part of the ring is flat so I decided to use the octagon shape I made in the previous step to make a hole in the ring to cut the top part. After positioning the shape on where I wanted to make a hole in, I grouped the element with the whole ring.

I was successful with cutting the top surface of the ring however, when I grouped my ring, the gold inner part was also grouped and was combined with the outer part of the ring to make one whole shape. Later, I realised that I can copy the gold inner part of the ring and match it with the ring afterwards so that it won't be grouped. I made sure that I changed my angle and perspective so that I can adjust the gold inner part to perfectly match my blue outer part.

After creating the hole, I copied the octagon element from the ring that I created a copy earlier just in case, and combined it with the ring. I adjusted the sides, height, and also added a 2.5 bevel because the original sapphire ring artefact has a bevel as well.

After finishing creating the ring shape, the final step is to create a curving of Caligula's wife, Caesonia's portrait to add on the surface of the ring. For this, I used the scribble shape and drew the portrait step by step while looking at the picture of the portrait several times. I also used the eraser tool to erase a slight bit so that the shape won't have sharp edges. After creating the basic shape of the portrait, I used the erase shape tool to recreate the curved taste for the hair accessory and clothes. At last, I stacked the portrait shape to the surface, adjusted the size, and grouped it to make a hole so it would look like as if it was curved on the surface of the ring.

This is the final product of the 2000 year-old Sapphire Ring replica created in Tinkercad.
