For my prototyping process I started with creating my design on TinkerCad, my inspiration for my wind up toy sis Mater From Cars. I used basic shapes to create Mater's body and for details I imported his truck logo, and facial features into TinkerCad and grouped them to his body. For my design the challenging part of creating a car is adding two more wheels to my 2 - wheeled motor. the idea I have in mind is to laser cut a small block of wood with small hole to insert poles. This would act as a base and from there I will 3D print wheels and brackets to hook both my block of wood and motor together, from thereI would use hardware to attach it to Mater's body.
After Creating Mater, I had to think of a way to incorporate the motor into my design. My first idea was to slice the body of my design in half and use sinkholes and hardware to fit it together. In TinkerCad is used holes to slice the body and copy and paste sinkholes into my design from my previous ellipsoid project.
Next, I used Cura to print my first prototype.
After printing I noticed that the hook in my design on TinkerCad had fallen off and broken. This was not a major issue because I realized that the car looked better without it.
After printing I also realized that the holes for the hardware did not match up with each other. in addition to this, the facial features and side logo did not print visibly. I had to go back into TinkerCad and readjust these details so they were raised off the body enough to be visible.
For my second prototype, I decided to scratch my first idea. Instead of cutting Mater's body in half, I chose to keep it as a whole and discard my sinkholes because instead I wanted to create a cavity underneath the body of my design for the motor. In doing this I grouped my design back together and used a "holed box" to cut out my cavity underneath the body of Mater.
from this photo you can see the full body design rather than the two halves. I wanted the entire body of the car to sit flush against the motor.
The cavity underneath the body of my design was not large enough or high enough for the motor to sit flush. In attempts to fix this problem I tried filing the excess filament away, but it was not working well.
The positives to this print are the facial features and the logo printed visibly and clean.
After going to Cura again and printing my design, I ran into another issue. The motor did not have enough space to be raised up into the cavity. the measurements for the width of the motor were off.
For my next prototype, I want to raise up the cavity space for my motor and also add wheels and an axil to the motor of my Mater inspired wind up toy.
