After receiving my prototypes back the diameters were too small and the knobs were unable to fit the potentiometers. I tried to file down the sides of the knobs so it would be easier to slide the knobs on, but they still did not fit. In my final knobs I made both diameters larger and made the cube smaller on the 5k because it was bigger than I imagined, after seeing the prototype.

I completed my first two prototype knobs for the 1M and 5k potentiometers. Openscad was a little difficult at first because I was new to the platform but I definitely have a higher understanding of it now. For my knobs I wanted them to be the same shape and I though it would be very cool to create diamonds. Little did I know that rotating a cube into a diamond was harder than I thought it would be. I did some troubleshooting and research and finally with the help of Ms. Riley, we figured out how to turn the cube just right. When troubleshooting I tried using translate and rotate but the cube was only turning right and left, and not up and down. To turn the cube into a diamond you have to use rotate and set an 'a' value and 'v' value. It then came up to just trial and error with plugging in degree values for 'a' and 90 ended up perfectly rotating it. I then set the measurements for the cylinder inside, and made sure both diamonds were fairly larger than the cylinder inside. I hope they will turn out well because I made sure to make the diameters of both cylinders a littler larger than the measurement.

Scaling was my main problem in my puzzle project. I made multiple faulty prototypes, with the last one weirdly fitting on one side but not the other. Too ensure my next printed puzzle would fit I made sure to size down .1mm from the inside length and width measurements of the tin taken with the caliper. My puzzle was printed all one color out of time constraint, though I really love how it looks so monotone and its transparent dark gray color looked very nice!
When we were assigned to make a puzzle for our tin I immediately thought of making a monogram. I really like the idea of my initials as puzzle pieces on the bottom of my tin. I began in Illustrator and found a font that I enjoyed. After doing the normal steps for text, I placed my initials into the outline of the tin as another layer. Once I followed all the puzzle directions in illustrator I was ready to place them into Tinkercad. But I realized that the line for the 'D' did not have an influence and was not a part of the large puzzle piece. With the help of Ms. Riley and Ms. Dixon I fixed the problem. There were many trial and errors but one night after playing around on Illustrator I created the two separate pieces I wanted and figured out the tolerance of the 'D'. I did this by putting the two pieces into a separate layer, dividing them with path finder and then clicking the inside piece and doing the tolerance one more time. It was a much smoother ride after this bump in road. With the given colors the 3D printer was using, I decided to make the initials white and the outline blue because I think they will contrast well together. Next I saved the initials and outlines separately as SVGs. And following the steps I successfully put them into Tinkercad and then saved each as an .stl. The last step on the computer was to scale and slice each in Cura. I learned that when using Cura you have to have patience. I then saved both as gcodes and moved them into the SD card. I had left my puzzle on the SD card in class so when I came next class it would be printed. However, I had made a mistake on my files and it printed with a brim and the size was larger than the tin. What I did was, I went into Tinkercad and scaled my files again with the right scale numbers by creating a rectangle around each and reading those measurements. I saved each as an .stl again an imported them separately into Cura and changed the Build Plate Adhesion type to skirt, which is just a line connecting around when the puzzle is being printed, instead of a thing boarder connected to the pieces. Repeating the Cura steps with correct scale, I was able to save both as gcodes and place them into an SD card to be printed. Now I am just waiting for my puzzle to be printed! For this Omni Animal project I took time to brainstorm my ideas. There were multiples animals and objects I had in mind, and I ended up with a kangaroo as my animal. The way I chose to incorporate the box, was as the kangaroo's pouch. Since the body is larger than the pouch, I sketched the body according to the size of a pouch(box) I wanted. First my kangaroo was too big, reaching a height of over a foot long. Drawing a life size version helped me imagine the look of the animal. Following, I came to the realization that I wanted a hinge box for the pouch; however, if I wanted it to be connected to the main body of the animal, I would have to cut large holes for the hinge to move through. So after talking to my teachers and peers, it was concluded that there would be pegs between the box and the legs to allow flexible space for the hinge. I chose my measurements of the kangaroo pieces with a ruler and normal white paper. By bringing in the scans into AI, I was able to easily convert the drawings into a vector file with the help of a shared tutorial doc. Along the way we completed a pen tool exercise which helped me when it was time to create the cut layer. I chose to raster the fur marks, score the eyes and nose details, and obviously cut the body parts. One problem I had was resizing the tier box file. Since it was originally three boxes connected by hinges, I had to figure out which parts I needed from the top and bottom box to create one hinge box. With help from my teacher I modified my box measurements because since the holes and hinge sizes cannot be moved, only one side of the box could be changed. The hole and hinge placement are contain specific screws and parts that have to stay constant in order for the hinge to work. Therefore, I chose to make it wider and used a rectangle to fit each side to the new measurement. The next step was using the laser cutter to create my omni animal. The parts turned out well, and I really liked the rastering. One difficulty in this project was making a proportional animal because there are many different parts. I used the rastering only on one side, so you can see the animal from a profile view. A designing error I made is the box because I by accident only changed the width of the sides and not the height too, so I have to re-laser the I am using my artistic license in this project because the omni animal looks like a hybrid of different animals, and not just one. In the final steps of creating my omni animal, I glued and screwed the animal together with the hinge box as its pouch. There was one more fault that I had to fix, which was the sizing of the box sides. I had not realized that the measurements for the sides were be a perfect square with the width length on all sides. After they were cut again I glued the box pieces together and used small pieces of the round wood sticks hold the box connected to the animal. Although my omni animal did not turn out exactly how I imagined it, I had fun in the process of making this hybrid animal! |
