3D Printing CoronaBell

I knew I wanted to try and create a working prototype of CoronaBell, and being fortunate enough to have a 3D Printer at home, I decided to created the 3D Model and print it.

Although I have a 3D Printer, I don't have any 3D Modelling skills. I usually use 3D Models from the internet to print. However, I knew that I would have to create my own model, as this doorbell was going to resemble that of the logo.

To create my 3D Model, I used an online application called Tinkercad. This is a simple online 3d modelling tool, used by beginners to help create 3D Models. Although this program is for beginners, it is very advanced, in terms of measurements and alignment. I also designed a faceplate to go alongside the doorbell, so people knew how to ring the door bell, without touching it.

As can be seen below, this was my 3D Model after designing it in the Tinkercad software:

I sent my 3D Model to my printer, adjusting the settings to fit the material I had for the project - in this case, Black PLA. Three and a half hours later, the print completed, and this was the final piece attached to the snap platform:

I then removed my 3D Print from the snap platform and inserted the Ultrasonic Sensor into the eye slots. During my design I measured the Ultrasonic Sensor that I had, then made the gap 0.2mm bigger, so that the Ultrasonic Sensor fit into the eye-slots, without having to be stuck down, creating a firm fit.

As can be seen on the photograph above, I added to holes in the top and bottom circles, to allow screws to attach it to a wall/surface.

To improve on my design, I am going to add white colour to the mouth using Tip-Ex, as I did not have white PLA to be able to print this. As the mouth can only be noticed in certain angles and lighting.
