Module 3: SHU Engineering Cube Design

Measurements:

We found that our real life cube model has different dimensions than online Tinkercad version. We measured our real life cube to be 1" in length on all sides whereas the online version is measured to 1/2" on all sides.

Design Explained:

When taken apart it becomes obvious how the cube with the ball inside was created. Starting off as a simple cube, the creator then went and placed a cube in the center of each side and extruded it to it went all the way through the original. After these steps had been completed, a sphere was created and simply placed in the middle of the cube.

Similar Design Explained

The is a cable saver, and this is very similar to our design because we both have the same idea on saving the cable but different designing ideas. To me, this image looks like it was created with a big rectangle that is cut down a lot, almost like a longer/skinny cylinder, on one half and the other half was cut down a little, like a shorter rectangle that curves in at the top. They cut out the middle with an oval shape piece that was bigger for one half and smaller for the other.

Design Limitations:

Sphere:

We decided to use a sphere as our design because we knew the printer could have trouble drawing curved surfaces.

Above: We first placed the ball inside the sketch

Above: We then placed a ruler on the sketch to get to dimensioning

Above: We placed dimensions on the sketch to spec. it to the right size; 1/2"

Above: Finished Sphere product

"Spaghetti String":

Another limitation was that 3d printers are probably bad at generating shapes that deviate from their usual Cartesian grid, so the idea of a "spaghetti string" shape was made.

We obviously didn't make a string of spaghetti, but the disconnected/curvy/long shapes should pose a problem for the printer's rigid system of creation.

Long Rod:

Another limitation the 3d printer has is that when it comes to printing models with a great length, depending on the 3d printer, it can either emerge fine or parts of the model can be crooked or can't be printed at all.
