3-D Game Pieces for the Video Game Ouroboros King (6 Pieces)

My name is Olivia Sharp, and I am a senior at Dublin Jerome High School. This is an Instructable on how to create 6 different game pieces from the video game Ouroboros King in Fusion 360. Ouroboros King is a game that combines the strategy of chess with the build creativity of roguelike games. This game recreates chess pieces, and I wanted to physically create them to be 3-D printed.

(You can check out the video game here: Ouroboros King Steam page)

The only materials needed are:

• Fusion 360
• A standard Bishop, Rook, Knight, and Pawn chess piece
• If these can't be found, you can Google the sizes of each piece, or follow the general size I used
• Measuring device
• Paper and pencil to design what you want the pieces to look like

That's it!

This project assumes that you understand the basics of using Fusion 360. Any measurements in the screenshots are in millimeters. Also, each picture should have notes giving extra details.

This is how to create the base of the Jester Pawn.

1. Sketch the base. This should resemble a pawn as close as possible, but creativity is always welcome!
2. Tip! Make sure your shape is closed (blue inside) and that the middle of the pawn starts directly on the y-axis
3. Use the revolve tool to create the 3-D shape by selecting all of the sketch then the y-axis
4. The base is complete, lets move on

This is how to create the jester part of the jester pawn

1. Create a circle. The first circle should be bigger and start on the origin plane perpendicular to the pawn sketch. The circle will appear to be in the middle of the pawn's head
2. Create a second circle. This circle will be much smaller and act as the point of the hat. You will need to create an offset plane off of the plane of the original circle
3. Next, create 2 arcs that connect the edges of the big and small circles. This will be on the same plane that the pawn sketch is on. You will need to make sure to use the intersect tool to confirm the circles are connected.
4. Select the loft tool. Select the big circle and then the small circle as profiles. Then, click the 'rails' button and select the line guides created in step 3. This will create a 3-D shape!
5. To get the 'ball' at the end of the hat, select the Sphere tool from the menu and then select the face of the small circle. Adjust the sphere to whatever size looks the best.
6. Finally, select the mirror tool to finish the hat. Make sure to select the cone shape and the sphere for the 'object' selection. Mirror the objects over the XZ plane (the plane where your big circle is located).
7. The Jester Pawn is Complete!

Both the wizard and the archer use the same base. So we will just need to make one base, then change the hats.

1. Sketch the base. The Bishop is longer and more rectangular compared to the pawn.
2. Revolve the sketch. Just like we did with the pawn, select all parts of the sketch and then the y-axis
3. The base for the wizard and archer is complete.

This is how to create the 'Robinhood' hat on the Bishop Base to make it into an archer

1. Create an offset plane from the XY origin plane. This should intersect the top of the Bishop's head.
2. Create an oval shape that will make up the shape of the hat. This is the bottom-most section of the hat
3. Create another offset plane, this time raising it slightly above the previous plane. Repeat step 2, making this oval smaller than the first.
4. Keep creating ovals above each other until you get the general shape of the hat. I used 3 ovals.
5. Select the loft tool and select the profiles, bottom up. This shouldn't require rails, so no need to make any!

Now that the hat base is complete, its time to add the feather!

1. Create a plane that intersects the hat at an angle.
2. Create a feather-like shape on this plane. It doesn't have to be very detailed.
3. Extrude the shape on both sides until it looks like it is in the hat.

The Archer Bishop piece is complete!

This also uses the Bishop Base from Step 3. Convenient!

1. Again, create a plane that intersects the top of the head. Sketch a large circle on this plane. This is the rim of your wizard hat.
2. On the same plane, sketch a smaller circle (about the size of the widest part of the Bishop's head). This is the base of the top of the hat.
3. Extrude both circles until they look like a hat brim.
4. From the XZ origin plane, offset a plane to where you want your witch hat to end. Sketch a small circle above everything else so far. This becomes the point of your wizard hat.
5. On the YZ origin plane, create guide lines that connect the smaller flat circle and the point of the hat.
6. Finally, use the loft tool on the smaller circle in step 2, the smallest circle in step 4, and select the lines from step 5 for your guide rails.

The Wizard is finished!

This is how to make the Viking Rook, both the body and the hat!

1. To create the base, we will do the same thing that has been done for the other bases. Create half the shape of the rook then revolve it around the Z-axis.
2. Next, create a circle in the middle of the Rook's head, this circle will be on the ZY origin axis, which is perpendicular to your sketch.
3. Create a smaller circle parallel to the first circle by using an offset plane. This circle will act as the sharp point of the horns.
4. On the parallel plane create guide rails as we did in the other pieces. Make sure both lines connect to the point in the middle of the smallest circle. This ensures that the horn has a point instead of being flat.
5. Finally, mirror the body of the horn on the Z-axis, the same as what we did for the Jester Pawn.

Your Viking Rook is complete! The next piece is a bit more complicated, so get ready!

This is how to make the horse-shaped base that will be the starting point for both the Unicorn Knight and the Pegasus Knight.

1. The very base will be started the same as the other pieces. Create a rectangle with half of a trapezoid on top.
2. Revolve this shape around the Z-axis. This completes the base of where the knight sits on top.
3. Next comes the actual horse. The sketch is on the same plane as the base. It can be hard to create a horse from scratch, but these are the steps I used.
4. Create a rectangle base.
5. Make a circle at the halfway point of the rectangle. This is the cheek of the horse, so adjust it up until you reach the height you want your horse to be.
6. Create a second, smaller circle whose midpoint lines up with the edge of the rectangle. This will be the nose, so make sure it is lower than your 'cheek' circle.
7. Use the arc tool to connect the top corners of the rectangle with the 'cheek' circle. The outside arc should connect at the '2 o'clock' position, while the inside arc should connect slightly before '6 o'clock'.
8. Connect the edges of the 'nose' using the line tool. The throat line should connect to the connection point of the arc and circle. The nose bridge line just needs to connect somewhere near the 'top' of the head.
9. Now that the general horse is outlined, we can add details like the ear and mane. These aren't super specific, so make them look however you'd like!
10. Next, we must extrude out the sketch to make it into an actual shape. Select every part of the sketch and use extrude to make a 3-D shape. Make sure to have it extruded on both sides, otherwise, our game piece would be lopsided.
11. Now comes the final part of the Knight base. View your sketch again and select all of your horse sketch except for the rectangle on the bottom. Select the extrude tool again, but instead of extruding, make sure it is on the 'cut' option. This will create a space inside the blocky horse, to instead make it look like 2 horses together.

The Knight base is complete! The next 2 steps detail how to make the horns for the Unicorn Knight and the wings for the Pegasus Knight.

This step is for adding the unicorn horn to the Knight base.

1. Create an off-set plane from the XY plane. Line it up so it intersects the forehead.
2. Create a circle that lines up to be directly in the middle of the forehead. This will be the widest part of the horn, but it shouldn't break past the forehead yet. In other words, the sketch should still be inside the Knight's head.
3. You may have to include/project part of the forehead to ensure that your circle is in the middle. The purple lines are where I included the top of the forehead to line up the middle.
4. Next, create another plane, starting at the same plane, but going to about where the nose would start.
5. This circle should be higher than the other circle, as it will make the tip of the horn.
6. Finally, use the loft tool to connect the circles. Select the larger circle as profile 1. Then, select the middle point of your second circle to create the tip. Selecting the middle point ensures it is a point as opposed to being flat.
7. To finish, use the mirror tool to put the horse on the second horse. Since this piece is symmetrical just selecting the horn then reflecting it from the YZ axis should put it on the second horse!

The Unicorn Knight is complete! Next is the final piece, the Pegasus Knight!

This is how to make the wings on the Knight base to make the Pegasus Knight!

1. First, we'll need more room in-between the two horse, so you have to select the horse sketch and cut out about double the amount in step 7.
2. Once there's more room, select the YZ origin plane to create a sketch on. This plane is right in-between the horses.
3. To create the wings, start by making an 'L' shape with the line tool to outline where the wings start in the front.
4. This is the fun part! A bunch of feather shapes need to be created for the wings. You can be quite creative and make them look any shape you want. I made mine spikey and pointing up, but you could do a different wing style!
5. I created mine by using the arc tool and connecting two arcs together down the wings.
6. Finally, use the extrude tool to make the wings fill out the middle space. Make sure the tool is on the symmetrical setting.

You've successfully created all 6 pieces!

You might feel that some of your pieces are too blocky or sharp, and an easy way to fix this is by using the filet or chamfer tool to smooth the edges. Another way to fix your pieces is to play with the size and positioning of some of the shapes. Sometimes while creating you don't notice any wonky parts until the end when you step back.

Finally, thank you for reading all of the steps. Hopefully, I could help you recreate game pieces in the real world!
