Group assignment for machine week on group site

My part in the Machine week

We decided to to a tea machine. Here is the sketched I made.

I made the structure around the tea machine. Links at the bottom. I used 3mm plexy all white except the top, we wanted to have that clear so everything would be visible, the plexy was laser cut with a kerf of 0.1mm that way it would fit together without having to use glue incase we needed to take it apart again. For the bottom I used a 19mm plastic material that I milled in the CNC. Used a 3mm upcut for the slots that the plexy would go into and a 6mm upcut for the cut outs for the cup and bowl and for edge cut. Þórarinn had made a logo for us that I vinyl cut to have it on the machine.

To hold the servo on the machine Hafey made a fastening that goes into the holes already on the machine, she measured the servo and drew it up in Inkscape and put that drawing into Tinkercad, put it in the correct thickness and made a fastening around that and 3D printed it.

We used silicone covered wires to solder onto and connect it in the back.

I found out how many steps of the stepper and degrees of the servo would be needed, this would have to be adjusted in spiral 2 but this is it in spiral 1.
