This project was my final rotation, and I was able to start work on it a day early so I kind of went a little bit over complicated with it. I decided that I would do a coin holder that is in three pieces: A cylinder for holding the coins, a spindle and base for rotation, and an arm to hold on the top and push the coins. I started by drawing it in my notebook as always.
After this I constructed the object in Autodesk Inventor, put it into makerbot software, and 3D printed it.
The holes for the coins in the original print weren´t quite correctly sized, and filing the object did not seem to work, so I had to redo them in inventor and print it again, which I ended up scaling slightly incorrectly as well making it a bit too tall for the arm to be placed on (new inventor file is basically identical to the old one).
Overall, I believe that I learned the most from this project, probably because I messed up the most. First of all, something I knew in carpentry has now been added to my digital design process, measure twice, cut once. Not only did I mess up the scale for my second print I also witnessed others who screwed it up on a much worse scale, so I won't be forgetting that soon. I also learned that you have to increase precise real world measurements by 3% in inventor, and that using an edge file in the computer lab will not only not fix it, but also get you (rightfully) yelled at by Mr. Willhour? Overall the mistakes that I made taught me for the future, and I plan to try and fix/improve this design before the end of the semester.
