This week I started to work on the float again. At this point it was a lot more waiting for prints to finish, then testing them, then reprinting a new version. This meant that I had lots of downtime in the shop. With this time I did a little project for Mr. Christy. Mr. Christy is building a herb press that uses an 8 inch C clamp and a steel cup.

This week I finally got the CFD software to play nice with the new ROV model. to do this I simply just took out all of the hardware in the model, as it was just to much for the CFD software to handle. With this simplified the simulation was able to run over the weekend… if my computer didn’t lock itself. I had set it to not sleep, but forgot to set it to not lock.

This week the auger in the fish feeder broke. This meant I needed to fix it majorly, and not just reprint the auger. We eventually settled on reducing the length of the auger, by adding a bend in the pipe. This effctively reduces the torque on the auger as it doesn’t have to be as long. Another measure I took to reduce the torque was to increase the diameter of the auger, as bits of fishfood were getting caught inbetween the auger blades and the inside of the pipe.

This week I had to put the piston on the back burner, as I needed to wait for the O-rings to arrive. This meant that I was able to focus on something else for a little bit. I started assembling the battery holder which turned out to be a lot more difficult that I expected. The Formlabs Form 3+ resin printers that the shop has are bullet proof about 97% of the time, however that 3% of the time they are very very frustrating to work with and fix.
