Jammar Jack Ghost Clip

Project summery:

In this project, me and @mm@@r worked together with the goal of each creating two identical ghost clips. A ghost clip is a 13 cm by 6 cm creative alternative to your average paper clip

Problem Statement (goal):

With a partner, you will recreate your ghost clip using Solidworks.  You and your partner MUST have identical files that you create by collaborating on each step, one at a time. 

Assembly/construction Instruction section: 

1. Create a constraint box using a centerpoint box with “from midpoints” option selected, and centered from the origin. This should be made of construction lines

1. Later, we realized that the constraint box should have covered the entire body of the clip
2. We solved this issue by changing the dimensions of the constraint box to 11 cm, to make up for the 1 cm triangles at the top and the 1 cm semi-circles on the bottom

1. Create 6 identical triangles at the top of the ghost
   1. Each triangle should be one centimeter tall and one centimeter wide
   2. The bottom line of each triangle should be made of construction lines
   3. We had trouble making identical triangles, so it helped to use the mirror tool to assist in completing this section. We mirrored three triangles over the origin. 

1. Create 3 semi-circles at the bottom of the constraint box
   1. At first, we tried to use circles and the “cut” tool, but later we realized that arches were easier
   2. Each arch must be two cm long and one cm wide
   3. As you can see in the picture above, we had difficulty making the points of the arches exactly on the points of the constraint box. This led to the box not being fully filled in. 

1. Create two vertical lines
   1. One line should go from the bottom left most point on the far left triangle to the top left point of the far left arch, and be 11 cm
   2. That line must be mirrored over the origin

1. Create a circle for the eyes
   1. Create one circle that has a radius of 1.2 cm  and 4.5 cm above the origin, and 1.5cm away from the left edge of the constraint box
   2. Mirror this over the origin

1. Create the mouth
   1. Draw a vertical line, 1.2 cm away from the left edge of the constraint box, 4cm long, and the bottom point is 2 cm below the origin 
   2. Mirror over the origin
   3. Create an arch that goes from the bottom points of both lines that goes 1.5 cm down. 

1. Select the two vertical lines and the arch (the parts of the mouth) and use the offset tool to offset it 0.5 cm inwards. Cap the ends. 

1. Extrude the ghost
   1. Exit the sketch
   2. Using the extrusion boss tool, extrude the ghost by 0.10 cm

1. Engraving your initials
   1. Create a new sketch
   2. Create a horizontal construction line on the origin, stretching from one point on the inside edge of the mouth to another
   3. Move the line up to about ¼ the way down from the top of the ghost
   4. Select this line
   5. Click “Text Sketching Tool”
   6. Type your first initial, select the font “Impact”, center align the text, and set the font size to 1.5 cm
   7. Click the check mark
   8. Make a horizontal constriction line at the origin, from one side of the inner mouth to the other
   9. Move the line to about ¾ the way down
   10. Select this line and the Text Sketching Tool
   11. Type your last initial, select the font “Impact”, center align the text, and set the font size to 1.5 cm
   12. Click the check mark
   13. Select your sketch in the features tree
   14. On the features tab, select extruded cut
   15. Change the dimension in the menu that has replaced your “Feature Tree” to 0.0495cm

Design choices:

1. We created a paper sketch to outline what we wanted to put into solidworks
   1. This sketch is not exactly what we ended up doing, but we kept it similar
   2. We also created a set of instructions, which ended up not being very accurate, but helpful to use when we were modeling the ghost 

1. When we made the plan and guidelines, several things did not work the way we imagined. One major issue we realized was that using circles was not working for bumps on the bottom. This resulted in the points not being exact, which was a problem for us because we could not figure out why the sketch was not locked down. 

In the picture below, the sketch is clearly not filled in. For a few days, we could not figure out why this was until we looked at the points in detail and realized they were close, but not touching. It took us a while, but we managed to go through all the points and reposition them so they connect. Several places had this issue, including the bottom bumps, and the vertical lines at the edges. 

1. We also had trouble with the triangles. At first, there were slight problems with them being slightly wrong, and we just needed to add an “equal” relation. Unfortunately, that solution was short term, because when we solved the issue with the points, that messed the triangles up a lot. It took a while to fix things, but after creating a few and mirroring them over the origin, it fixed it all. 

1. The rest of the sketching went off fairly well without many problems. Before we printed, we put the model ghost up to the screen to find any differences, and we didn’t see any. Unfortunately, After printing it, we noticed a few problems.
   1. The eyes and the mouth were proportionally correct, but just about half a centimeter too high
   2. There were slight differences in the height of the triangles. 
2. Additionally, we deleted the construction lines that were needed in order to keep the “JL” in place on the ghost.
   1. This was problematic because it meant we needed to remake the letters  

Conclusion: 

Except for a few minor differences, such as the mouth and the eyes, our model was mostly identical to the original clip. Additionally, me and Ammaar’s ghost clips were completely identical. After creating the ghost clip, we were proud to be able to successfully create a model of it, and we hope that you will find a good use for it!
