Gadget Reflection

Gadget Reflections:

Nick's Gadget

My gadget came out way better than I had anticipated. The measurements for the most part are correct and the phone charger fits snugly inside. The printing quality came out very good for a smaller sized part, even though there are still some minor flaws. If I were to go back and redesign the part I would create smaller dimensions for the charger plug section and would decrease the gap used to get the cord in the gadget itself.

Marlon's Gadget:

My gadget didn't come out as I wanted it to be. Although it looked accurate to my original design, it was too big to place on my phone charger, and it was very easy for it to fall off.

Charlie's Gadget

My gadget still has problems relating to size and brittleness. This print was probably the right size concerning the circular clip side, but it was too thin in the lengthwise parts and the length itself could have been shortened. A redesign would probably include thicker parts in all areas, plus maybe shorter length.

Group Reflections:

Kangas: 1-3-1-3; avg. of 2

SHUMakers: 0-0-1-3; avg. of 1

Team Intl.: 2-3-1-2; avg. of 2

Pacha: 0-1-2-1; avg. of 1

Overall, we think that team Kangas and team International had the best designs with the 3D printed models. Their designs were actually functional compared to the other groups and had enough durability to properly function without breaking. The other groups either had designs that were too small and/or not properly functional.

Group Project Design Paragraph

Group Design Reflection

After meeting with all of the groups we came out with a few ideas to share. One idea is that no one can get their gadgets smooth while printing, this is a limitation of the printer and not user error. Another idea is that some groups are not using the most efficient methods of using their product, for example the bottle opener has it working the wrong way. The group creating the carabiner clip has the lever to the clip opening up the wrong way which could be problematic for the designs function.  

Nick Campana Gadget Design

Gadget Design Process

Above: I first started with a cylinder, then dimensioned it and placed another on top to extrude a hold thru. the part

Above: I then placed another cylinder on top with a work plane and resized and centered to to fit the charger plug.

Above: Just like before I extruded a second cylinder thru the top piece in order to hollow it out to fit the charger plug.

Above: Lastly I placed a box. I then resized this box and centered in and played with the dimensions in order for it to cut out an opening in which the charger could fit.

This design took me about 45 minutes overall and closely resembles the correct dimensions of a real iPhone Charger.

Module 3

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.

TinkerCAD Tutorials Summary

• In the Learning the Moves tutorial, we learned that we can move objects by moving them with the mouse or selecting the object and using the keyboard keys to move it.
• In the Camera Controls tutorial, we learned that in order to control the camera, we can scroll with the mouse or press and hold the right mouse button while moving the mouse to rotate the camera.
• In the Creating Holes tutorial, we learned that we can make holes so we can remove unwanted materials from models. 
• In the Scale, Copy, and Paste tutorial, we learned that we can move a shape into the workplane, make a shape big, small, etc., and copy and paste a shape on the workplane.
• In the Key Ring, Letters! tutorial, we learned that we can make our own custom models.
• In the Die on the Workplane tutorial, we learned that we can use the work-plane to our advantage when it comes to designing models.

Module 2

Module 1 Redesign:

We currently have two new design ideas in mind, both that would reduce the amount of material used, but with an unknown change in quality and effectiveness.

As a group we ended up choosing this design because it removes a substantial amount of material without risking the integrity of the product. This design takes out part of the core of the product, leaving a strong "spine" to connect the two connectors on the end.
