HOW TO MAKE YOUR OWN PINCER CLAWS

• Go to TinkerCAD
• Under 3D designs and click create design
• A new workspace will appear

​

Before we begin..

• We are going to go into Tinker CAD and familiarize ourselves with the work plane, the different tools and the different ways to move around the work plane
• To orbit, sue the cube tool located on the top left-hand corner
• To pan, hold down shift + control + left click and drag
• To zoom in click on the +
• To zoom out, click on the -

​

• We want to keep in mind that each big square is equal to 10 mm length x width, so each little square is 1 mm length x width

​

Making the curve of the claw

• Click on the scribble tool on the right-hand corner and drag to screen

​

• This screen is where we are going to create the curve of our claw pincer

​

• Create a thin U-shaped figure

​

• Click on done on the lower right corner

​

• Dimensions:

length = 24 mm

width = 9 mm

height = 12 mm

​

Creating the Handlebar

• Is made up of a rectangle and an oval

​

• Drag the square shape to the work plane

​

• Using the gray squares, we are going to modify the shapes dimensions:
• Length = 31 mm
• Width = 5 mm
• Height = 7 mm

​

• the bottom portion is made by connecting two semi-circles together

​

• Rotate the shape 90 degrees so that it is standing up by clicking on the arrow

​

• * we can use the oval shape that is already provided for us, but this gives us a chance to learn other tools and shortcuts that may be needed for future projects *

​

• Select the object and click on control/command + D to duplicate the object

​

• Use arrows to move your object so they are side by side

​

• Click on the shape and use the rotating tool located on the bottom to rotate the shape 180 degrees

​

• Now that they are facing each other, we are going to use the ruler tool to align these shapes together

​

• Click on the ruler tool and drag the tool onto the work plane, lining up the circle over the gray square

​

​

• Your work plane should look like this

​

• Click on each shape and look at each shapes dimensions. Notice the green arrow on that is appearing when we click on the shape on the right-and side

​

• Click inside the box and change the number to 10
• We should then see that the two shapes are now stuck to each other

• Now that they are aligned, click on the x button to get rid of the ruler
• If you hover over the button, it should appear red

​

• Your shape should not look like this
• We need to get rid of the line in the middle

​

• Highlight both shapes and click on the group button

​

• Now we have a perfectly grouped and aligned circle

​

​

​

​

Create an oval shape

• Drag on the gray edges until you make a long oval shape-like figure

​

• Dimensions:
• Length = 21 mm
• Width = 6 mm
• Height = 7 mm

​

• Rotate the shape 28 degrees and group the shape with the other piece of the handlebar

​

Grouping all the shapes together

• Take the U-shaped figure that we created and slight overlap the shape on top of the handlebar

​

• Highlight all the shapes and group them together using the group icon

​

• Drag two cylinders to the work plane
• Height = 7 mm
• Width = 3 mm
• Length = 3 mm

​

• Make each circle a hole that we can cut out

​

• Place the two shapes in the lower handlebar, making sure they are equal in length

​

• Group all the parts together and two holes should have been created

​

Duplicate

• Click on the shape and on your keyboard press command/control and “D”

​

• Use your arrows on your computer to move the shape, so that they are next to each other

​

• Click on the mirror icon located on the tool bar and click on the arrows to flip the second shape 180 degrees

​

Final Product

• You have now made your own pincer claws!!
