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.
