SUMMARY 

 Are you a diehard fan of the Celtics, just love basketball, or like this clover design? Meet this fun awesome telescoping 9.2 cm × 9.4 cm × 2.0 cm clover that moves intricately with a hypnotizing design. With a fidget like this, your hands will be satisfied and you will fall in love with the patterns. During this project, I worked with William who was an absolutely amazing partner.

LESSON PLAN AND ACTIVITY 

Your task is to develop a telescoping fidget object by using the skills of sketch offsets and drafted extrusions or cuts. Your partner and you will provide feedback on each other's designs while helping each other troubleshoot and problem-solve. You aren’t required to have the same design as your partner but doing so will make the process much easier. 

ASSEMBLY/CONSTRUCTION INSTRUCTIONS 

• Pick a sketch and trace it in a 2d sketch
  • Make all arcs/ lines going in the same direction tangent
  • Make sure to fillet all the arcs connecting in the crevices of the shape

• Once the sketch of the outline is done, delete the original image that you used to trace.
• Start offsetting the sketch as many times as you can by clicking “Offset entities” and then checking the mirror box(Make each offset 0.1cm)
  • Make sure after your second offset, you delete any offsets in the stem of the clover. Also, there might be a line a little above the bottom of the stem so make sure to delete that.

• Once all your offsets are done (NONE IN THE STEM!) and they start overlapping, make sure to delete the overlapping arcs in the middle so your image looks like this(There should be no line at the bottom of the stem like there is in this picture).

• Then, select the outermost layer of the sketch and select Boss Extrude in the feature settings at the top. Make sure to set the height to 1.0cm and the angle to 15.00 degrees.
  • Also, for this first one, click “Blind” in the dropdown menu
• Next, select the 2nd most outer layer of the sketch and select Extrude Cut also in the feature settings. Select the “Through All” option in the dropdown menu and make sure you are cutting into the extrude. If you aren’t, then click the reverse button next to the dropdown menu. Make the height set to 1cm and the degree set to 15.00.
• For the next couple of steps, alternate between steps 5 and 6 but when you extrude and cut, select “Up To Surface” on the dropdown menu and click on the outer layer of the sketch
• Cut and extrude until there is no space to (If there are small holes in your areas where you can no longer extrude or cut, it is fine).
  • Your Feature tree should have a similar pattern to this(Without Mirror at the Bottom):

• Once done with that, your shape should look like this:

• The last step is to mirror this object by first going into “Features”, clicking “Mirror Entities”, clicking the “Front Plane”, and then clicking the dropdown “Bodies to Mirror”
  • first going into “Features”
  • clicking “Mirror Entities”
  • clicking the “Front Plane”
  • clicking the dropdown “Bodies to Mirror”
  • Highlighting over your shape
  • Checking the  “Merge solids” option
  • Clicking the checkmark when you see a yellow and blue preview of the mirror
• You are now done and ready to print your model! 
  • It should look like this from the front

DESIGN CHOICES

The inspiration for this clover comes from my love for the Boston Celtics which is my favorite basketball team. My wish is to give this clover to my favorite basketball player ever to touch the court: Jordan Walsh.

During the design process, this organic shape required me to be very precise. This included me having to fillet all arcs in the corners of the clover.

I was able to print my first Model but it was very small and there were only 6 extrudes. To fix this I scaled my original sketch to 1.25 times the size of my previous sketch which allowed me to have 8 extrusions and a bigger design overall. (There ended up being small holes on each of the 3 parts of the clover because I could no longer extrude/cut but this didn’t really affect my design)

Also, to experiment with which degrees work best, I created a 15-degree, 20-degree, and 25-degree model. I first printed the smaller model with 6 extrudes at a 15-degree angle and it was fine. Because the smaller model came out well, I also decided to print the larger model with 15 degrees as well. As I expected, the model came out great and there was no need to use the 20 or 25-degree model.

After printing the model I came to the conclusion that if you would like your fidget to shake/ telescope faster, the smaller model works better, but for a louder sound, the bigger model(1.25x) works best.
