Regarding the 2 in 1 package of regular wet towels and sunscreen humidified towels, we decided to work on the package itself.

The main requirement is that there is a division between regular towels and sunscreen towels, so the contents in each don't get mixed, something similar to what can be seen at the image on the right.

With that design in mind, we went to autocad so we could digitalize our idea.

The first design iteration of the sunscreen dispenser can be seen at the week 10 page. A more clear design can be seen right of this text, with the wet towels below the sunscreen bottle for an easy to use alternative to apply the sunscreen.

The other choice we have is as seen below this text, where the towels are placed in the top side instead of bottom. The intention of doing this is that the user simply flips the bottle and then the towels will be humidified with the sunscreen. A small sheet would be placed in between so just a bit of the sunscreen goes by, not humidifying the towels too much.

A virtual design has been done with software Rhinoceros, as shown on the right side of this text.

Regarding sizes, the idea is that the towel part has 2cm of height, the bottle 6cm and the dispenser itself around 3cm.

The width and length should be around 3.5cm.

Ideally, this will be made with photochromic material, so after some time has passed, the bottle will change colors reminding the user it's time to apply sunscreen again, as after 2-3 hours after the first usage protection is close to zero.

We also made a virtual design of the base of said dispenser, where, in theory, the wet or sunscreen towels would go at.

We used thursday class to try and print both designs we had ready for that moment: the base and the 2 in 1 package of wet towels and sunscreen-humidified towels.

However, we had issues when opening the .stl file on the Repetier Host software, as the scaling was wrong and both objects appeared way too small.

After modifying both files (stl and .dwg autocad file) in rhino, checking the units, and seeing that the issue was still there, we discovered that for some reason Repetier Host was taking the units in milimeters and not centimeters, so scaling by 10 fixed the issue.

Due to time, we printed only the small towel "dispenser" for the sunscreen dispenser, as the box would take upwards to three or even four hours. Even then, the base was not ready until friday.

When picked up, first thing we noticed is that it might be too small. Still, we all felt proud as this was our first physical prototype of the product.

On thursday there was also a new and finished dispenser prototype on rhino, so when picking up the base of the dispenser, we left printing both designs so we could pick them up on monday.

However, a mistake was made when sending the .gcode file: the temperatures were not the correct ones, so in the middle of printing, the design got detached, as seen below so at least one of us had to go on saturday and print them again, this time with the right settings.

Also below we see the start of the printing of both prototypes, this time with the right settings. This designs would be picked up on monday.
