Day 8: 6/1

 First day of June!

Things I need to do:

• Design cylindrical holder and 3d print it (DONE)
• Level the xyz robot
• ask Xiaobing if the perovskites will degrade (is it just FTO and perovskites that will or is it the entire cell that will?
• Ask who runs the nitrogen glove box

Based on the meeting with John and Likai, we might need to:

• make our own dry box
• store it in the dry nitrogen box
• life cycle for 1000 hours
• have it at 85 C for cycling

Interesting source I found for the cylindrical holder, in which I can add a spring: https://www.servomagazine.com/magazine/article/make-a-spring-loaded-pen-holder-for-your-cnc-router-for-5 

I designed the cylinder and tested multiple cylinder diameters out to get the right fit. I then made the cylinder thicker so I could drill a screw to pin the rods down, and 3D printed it.
