- Taking the center of the gear, create a circle of 10 millimeters in diameter and with extrude give a distance of 8 millimeters, now must be made the hour indicator, in this case it is to each one's preference how to design. For this case a circle of 15 millimeters in diameter and a rectangle of 15x45 millimeters in diameter is used, finally details are made with 3-PointArc and other strokes as shown in the image.

## Step 11: Let’s Work in Details

I create a support for the displacement rod, for this we create a rectangle of 10x4 millimeters and in the corner we put a circle of 4 millimeters in diameter, then use the extrude command on the circle and giving a distance of 6 millimeters. Then we create a square on the circle of 4 millimeters per side, again we use the extrude command giving a distance of 8 millimeters. I take a base of the generated rectangle and on it and mark a rectangle of 4x2 millimeters for which in the corner we mark a circle of 3 millimeters in diameter and make a cut of -4 millimeters with the command extrude.(Image S11_01_01, S11_01_02, S11_01_03, S11_01_04, S11_01_05, S11_01_06, S11_01_07, S11_01_08 and S11_01_09)

Select component 5 and make a cut of -3 millimeters with extrude.(Image S11_02_01 and S11_02_02)

## Step 12: Displacement Rod

- New component.
- (Image S12_01)

- I made a circle with 3 millimeters in diameter and using the extrude function, I gave a distance of 147 millimeters. Then draw a line to 58 millimeters and at the end of this draw a rectangle of 12x8 millimeters. After the rectangle I draw a line of 41 millimeters and a rectangle of 12x8 millimeters. Selected the 2 rectangles created and by the extrude command we give a distance of 1 millimeter.

## Step 13: Rocker

- New component
- I draw a rectangle of 140x21 millimeters, in each corner made the following strokes: rectangle of 40x21 millimeters, rectangle of 10x21 millimeters, rectangle of 40x9 millimeters. Having these strokes used the command 3-Point Arc and later we draw a rectangle of 40x8 millimeters.
- (Image S13_02_01, S13_02_02, S13_02_03, S13_02_04, S13_02_05, S13_02_06, S13_02_07, S13_02_08 and S13_02_09)

- I made square marks of 2 millimeters per side, this part is where weights are hung to balance the clock, again we use the 3-Point Arc command and we eliminate ('t') those lines that we do not need. Then use the extrude command on the generated figure with 6 millimeters of distance.
- (Image S13_03_01, S13_03_02, S13_03_03, S13_03_04 and S13_03_05)

- Proceed to one of the faces of our generated piece, to create a hole where it will pass through our sliding rod. Create a rectangle of 3x25 millimeters, now in the corner of this created a circle of 3 millimeters in diameter. With the extrude command cut a distance of -10 millimeters.
- (Image S13_04_01, S13_04_02 and S13_04_03)

## Step 14: Weights.

- New component
- (Image S14_01)

- Generate the weights to balance the watch. First create a square of 16 millimeters per side and with extrude we give a height of 12 millimeters.
- (Image S14_02_01 and S14_02_02)

- Draw 2 rectangles in the top of 16x4 millimeters and in the part of the center we generate two circles with a diameter of 2.5 millimeters and we give them a height of 5 millimeters. Change the axis of work to make a circle of 1.5 millimeters in diameter, which will make a cut in the circle of 2.5 in diameter, this is to be able to insert a thread or another element to hang the weights.
- (Image S14_03_01, S14_03_02, S14_03_03, S14_03_04, S14_03_05, S14_03_06, S14_03_07 and S14_03_08)

- Move the piece to its corresponding place and duplicate the piece
- (Image S14_04_01, S14_04_02 and S14_04_03)

## Step 15: Details

- Used extrude in the rod adding a distance of 10 millimeters.
- (Image S15_01)

- Select the gear body 1 and extend the teeth of the smaller gear to make contact with the gear body 2. Giving a distance of 20 millimeters.
- (Image S15_02_01 and S15_02_02)

- Let's try some details, which are displayed in the images. These are details like a spring and give a better finish to the screw holes.
- (Image S15_03_01, S15_03_02, S15_03_03, S15_03_04, S15_03_05, S15_03_06, S15_03_07, S15_03_08, S15_03_09 and S15_03_10)

## Step 16: The Roman Numerals

To dial the numbers, in our case are Roman numerals and is taken into account as were the clocks formerly. For the design I simply take into account 4 important numbers, each 90 degrees corresponding to the numbers 3, 6, 9 and 12. Following the steps of the images can see the realization of each of the numbers, you can change it to your liking

## Step 17: Send to Print

## Step 18: Wood Parts

If you do not have 3D printer, you can make with wood or the material that you think I leave pictures where it was made in wood

Good luck!!!!
