Alcohol Dispenser

In this tutorial on designing an "alcohol dispenser", we used "Autodesk Fusion 360". If you want to build, you also need an ultrasonic motion sensor and a servo motor as in the picture.

To create side A, we placed a 126mm horizontal baseline followed by 5 28mm vertical lines interspersed with 4 3mm horizontal lines.

In order not to speed up the process, we will create a 15mm line in the center of the base. We know that this is the middle when we get the triangle symbol with x.

Click "Mirror" (Create) and select the lines to copy after selecting the lines you want to use as a reference (line in the center of the base) and finish.

So we take another 12mm horizontally from the baseline. Finally, we place it in a rectangle 24 mm long by 3 mm high and repeat step 2, this time selecting the lines that make up the rectangle.

Then we close the figure and finish the sketch.

To convert our figure from 2d to 3D, we will use "extrude" (create) and give it a dimension of 3mm by selecting the figure without the center of rectangles. If we also want to change the appearance, we click on "Appearance" (Edit) and give it the desired appearance.

In the same way, we will make sides B and C (the dimensions are given in the photos).
To insert circles we will use help lines.

The last piece has a variation of rounding in some corners; For this we use the "fillet" function (Modify).

If we want to do this with a project, we first need to load an image of our choice (preferably in dxf format) and paste it.

Then click Create Sketch and use a fit point spline (spline). Then we start to follow the image that closes at the end.

When we're done, we can either leave it like that or use "extrude"(create).

To put the parts together, we first place them on a new plane (don't forget to save the file first) and then drag the faces onto the plane. We use the "joint" option and we always join the middle edges that we want to join.
