Don’t get me wrong, trading Doc Roy shredded plastic for food was working. Slick and I were eating better and by belly was not rumbling any more. I still went back to the computer at night and looked up other things I could make. One caught my eye, called a recyclebot. It was a little robot that eats plastic and makes spools of filament for 3D printers. Whereas I could only get a few credits for giant bags of shredded waste plastic if I could turn it into good filament I could start making real money!
At first I was excited, but then I realized it needed a custom compression screw. Even with Slick’s help I knew the odds of finding one in the scrap heap were tiny. Back to the web – I found designs for a free rig that could make custom screws -- I could make it from scrap wood and an angle grinder. We saved up credits for a few weeks until we could afford the angle grinder from Doc Roy.
We had to make other sacrifices too. This was going to use some real power running the grinder, so no late night web surfing. Every drop of sunshine our panel could collect went to the battery. I ran the screw maker on my stored up solar power at night, while Slick was asleep, so the sparks would not scare him.
Luckily, he sleeps like a rock.
My compression screw came out perfect!
Now we were ready. Slick and I scavenged the rest of the parts and built a recyclebot from 3D printed parts I traded Doc Roy to get. It works! First, Slick throws plastic shreds into a hopper that we made out of an old 2-liter bottle I had cut the bottom off. Then this plastic went into an old pipe where it was moved forward by our screw turned by a motor. The plastic goes in and is transported down the shaft to get squeezed in between the screw we made and the pipe. This pushed the plastic into a ‘hot zone’ where I had wrapped some nichrome wire from a broken toaster. In went plastic confetti sprinkled by Slick’s little paws – out came a long piece of plastic spaghetti.
“No you can’t eat it Slick!”
This spaghetti has to have the right shape so I copied the plans to have it cooled in a metal tray by fans and pulled at just the right rate. I even found an old webcam I could use with some free software to monitor it. Finally, it was spooled up at the end by this perfect winding machine.
We sorted the waste shreds by color - and we made spool after spool all weekend for as long as the solar power held out.
Slick and I were first in line at the Doc’s trading post on Monday. Doc Roy was flabbergasted. Almost never did the jects bring him new stuff. He didn’t say a word. He took the spools gave me stack of credits and closed early. I could now get a day’s rations for a single spool! I might even start to be able to afford vegetables again. Yummy vegetables! Oh, how I dreamed of the elusive pea, broccoli and carrot every night as I picked dried bacteria protein from my teeth. No more, I think I may even have enough money to have Roy smuggle me out a salad.
I wonder if Slick will like it....
