  To start out, I think I was the very first person to book this machine so I was a little confused for a while. I was waiting for Peter to come in at 9 and tell me what I was looking at, but between the demo the day before and then, I wasn't sure what had changed. The Prusa Mini was in a different location. Did this mean it was hooked up to a different computer? I couldn't get it to connect to either.  Then I realized the cord we needed to tether the machine was entirely missing. Once everything was hooked up it went mostly smoothly. I managed to home to machine and use the modified black pen for an outline no problem. When I got to the infill, I wanted to use a different color, and this was my first hiccup. I couldn't get the top of the pen open, so I thought I'd try using one without the special compression mechanism. This didn't work out so well because when the pen made contact with the mesh bed, it moved the binder clip and misaligned everything. I would have ...

 To start my line drawing, I found a photo of a hand and applied some filters to make it quick to trace in Rhino. From there I made a quick line drawing of it and joined it all into closed curves.  Next I made a handful of cubes and arranged them in perspective view, before using Make2D on them to add to my line drawing.  Then it was just a matter of trimming and joining the curves together to make sure they were all closed and the sections I wanted to shade were separate from the rest. Then I messed around with some of the fills we made in Grasshopper last week until I found something to my liking.  When I found this set of diagonal lines looked nice, I baked them and trimmed the entire drawing to fit the 160x160 mm square. This was my final drawing:

 After completing the video tutorials, I decided that the shape we had created was very worm-like, so I took it upon myself to make an algorithm for an adjustable worm. In the future, I'd love to try to figure out the definitions to make the worm change in shape or size, but for now, I used some of the existing framework from the tutorials to make a worm with different-sized segments in it.  I started by adding circles to the base of each biarc and lofting them, following the biarc, to the other side. Then I created a definition to mirror both the lofted surface from the tutorial, and these new pipe shapes on the X axis. It looked like this in Grasshopper: I applied this new algorithm to a new set of parallel curves to make my worm. What I wanted to do after this was find a way to automate the conversion of these curves into solids and subtract the circles from the body of the worm. I couldn't figure that out, so I baked these pieces individually, then joined them to make poly...
