Puss in Boots Chess Piece

Description:

This assignment was a group project in which one member of each group was tasked with designing a chess piece in a full set. My group chose Shrek as the theme, with my piece being the rook modeled after Puss in Boots. The pieces are supposed to be scaled to fit on a standard chess board and should be sized correctly relative to the other pieces, as in the king should be the tallest piece, followed by the queen, and so on.

 

Process:

Step 1:

The first step is making the boots. For simplicity and symmetry’s sake, I made one booth and then duplicated it to make a pair. Start with a paraboloid shape suspended above the work plane in the dimensions shown. Then use a box that is a hole to cut the paraboloid in half, leaving a shape with a flat bottom. Lower the shape so it rests on the work plane.

Step 2:

Drag a cylinder into the paraboloid and align it so it is even with the back flat end. Using three boxes that are holes, align them on the sides and back of the boot shape so that the rounded edges on the sides of the paraboloid are in the boxes. Combine the shapes, making a single boot. Then duplicate the shape, placing them 5 units apart, and combine them so they are one shape (though they are separate and not touching.

Step 3:

The body of Puss in Boots is the egg shape. Drag the egg onto the work plane and above the boots. The dimensions of the egg are 33.12 x 21.92 x 37. Using the align tools, center the boots and the body shape, then combine to make one shape.

Step 4:

Puss in Boots’ belt could be done different ways. I chose to do a traditional belt, but it could also be draped across his body at an angle like a sash. If the latter is desired, the dimensions for the belt will have to be adjusted accordingly. Using the torus shape, adjust the dimensions to how they are as shown. Elevate the shape 20 units above the work plane and use the align tools to center the belt. Lastly, combine them to make one shape.

Step 5:

For the sword, I made it independently and then attached it to his belt. First I made the handle by combining a small cylinder and a small sphere.

To make the hand guard, I used 2 half spheres. The first half sphere was solid, while the second sphere was a hole. The second sphere should be one unit less than the solid sphere in ever dimension. Use the align tool so that the smaller half sphere is perfectly inside the larger sphere and combine them, leaving a hollow shell-like shape. Then use a paraboloid shape for the blade of the sword, aligning it to be centered with the hand guard.

Align the handle of the sword with the blade and guard, combine them, and place them onto the belt of the body at an angle. I adjusted the angle many times and every time the angle is adjusted, the angle of the shape is reset to 0°, so I’m not sure exactly what angle the sword is at relative to the work plane. The most important part, however, is making sure the tip of the sword is touching the work plane. 

Step 6:

None of the preloaded shapes in Tinkercad were fitting for the tail, so I utilized the scribble tool. Since the scribble tool is freehand designing, any shape can be used for the tail, just make it thin enough so it doesn’t look awkward. The important part, like with the sword, is that when the tail is embedded into the back of the body, the tail is resting on the work plane and not floating above it. 

Step 7:

Next I designed the head, specifically the mouth. I started with one small sphere and duplicated it, aligning the identical spheres so they were slightly overlapping. The height of the spheres is Then place a third sphere underneath the pair, combining all three and forming the basic mouth shape.

To finish the basic mouth shape, use a parabolic cone for the nose. Align with the rest of the mouth shape so that the nose is centered. Group the shapes together, forming the basic mouth shape.

Step 8:

The head is a simple sphere, but to minimize support, flatten the head by combining a box that is a hole with the head, so that the hat (step 9) can be attached using glue after the full piece is printed. Embed the basic mouth structure onto the bottom of the head. The eyes are spheres with dimensions of 6.31 x 4.7 x 4.81. Group the two eyes together so that the total length of the piece is 13.67 and partially embed them into the head, above the mouth.

Step 9:

To create the hat, use a MetaCapsule shape with the dimensions shown. Then align a flattened cylinder (in the dimensions shown) to be in the center of the MetaCapsule and group the two together.

Step 10:

The arms were the most tricky and time consuming part. Even in the final product, I think the arms could have come out better. For simplicity’s sake, I made one arm then duplicated and flipped it to make the other. Start with a cylinder and cap both ends off with half spheres. Group these pieces together and angle them at 45° To make the forearm, separately cap a flattened cylinder off on the wider bottom with a half sphere in the dimensions shown. The angle for the forearm is slightly less than 45°, see step 5 as to why I’m not sure on the exact number.

I utilized the pre-made hands for the paws for simplicity’s sake, putting them on the top end of the flattened cylinder. The hands are parallel to the work plane. Embedding the forearm into the upper arm wasn’t very exact, I just eyeballed it until it look alright, though I think I could have done a better job and am open to suggestions.

Next, duplicate the finished arm and flip the duplicate, spacing the arms evenly apart and grouping them together.

Step 11:

Embed the finished arms into the body, elevating them 32 units above the work plane.
