## Spanner

**Making a spanner on TinkerCad**

##### Now we are Designing a Spanner.

##### For **Designing a Spanner**, we divide it into **Three** Units.

- The JAW
- The HANDEL
- The RING

##### After dividing the Spanner into Three Units, now design all units one-by-one and then add (Group) all units.

**Design of the JAW of Spanner**

**To Design this Unit,**

##### – First Drag & Drop a Cylinder or Polygon from the Basic Shapes to the work-plane.

– Now give Hight of the Cylinder Shape (10mm), Diameter (30mm).

##### – Now put the Polygon shape on the Cylinder shape According to the given Picture.

– Now click on Polygon shape and then click on Hole to Merge the Both shapes.**Note: –** The Hight of Polygon should be more then Cylinder.

After merging Both shapes

– Now select all Shape, then click on Group Icon, for Grouping Both shapes.

Now JAW is designed, it will look like this.

**Design of the Handle of Spanner**

**To design the handle of Spanner**

**– First Drag & Drop a BOX Shape from the Basic shapes to the Work-Plane.**

##### – Now give Height, Width, & Length of the Box.

##### 1. Height of the Box (10mm).

##### 2. Width of the Box (15mm).

##### 3. Length of the Box (100mm).

**Now, Handle will look like this.**

**Design of the last unit of Spanner**

**To Design**** this Unit,**

##### 1. First Drag & Drop a Cylinder or Polygon from the Basic Shapes to the work-plane.

2. Now give Hight of the Cylinder Shape (10mm), Diameter (30mm).

3. Now give Hight of the Polygon Shape (10mm), Diameter (20mm).

**Note: –** The Diameter of Cylinder should be more then Polygon.

##### – Now increase the sides of Polygon.

##### – Now put Polygon shape on cylindrical shape according to this image,

##### – Then click on Align to centralize both shapes.

**Note: –**when the Middle Dot will become Grey in color, then the middle object is centralized.

##### After centralizing Both shapes.

– Now click on polygon shape, then click on HOLE to Merge the shape.

– After merging the polygon shape, Now select all shape, then click on Group Icon to group Both shapes.

The ring will look like this.
