### Feedback from Team O:
- Team O had several suggestions for us based on our current plans. They suggested a rotating tool head with different wheels on it. This did not seem feasible given the current mechanism constraints (as we then discussed, space is limited due to our caster mechanism). Though, on a positive note, they did not seem to think that it would be particularly challenging to manually change out the tooltips or wheels 
- They also had several ideas for improving our UI interface. We mentioned that it would be very difficult to program lines corresponding to differing tooltips, such that the UI "understood" and transmitted this info to Arduino/Ender. However, they suggested that different line colors, or even "dotted" / "square" line types might help visualize a design before sending it over. This wouldn't change the actual pathway / behavior but rather aid the user in understanding when they needed to change tool types out. 
- Team O suggested creating preset patterns that users can select and customize.
- Last suggestion was instructing the user to sketch in the UI, choose a tool tip, send it to the CNC machine, and then have the user draw another layer in the UI and select a different tool tip before sending to the machine again.
