Prototype (Upgraded)

• We had some problems with the previous prototype, and we upgraded them by solving the problems. 
• The first problem was the type of tube. The colour of the tube we have used for the previous prototype was white. We have purchased the one that is clear so the powders can be seen through the tube. 
• The next problem was that the number of tubes we had to produce. For three different amounts of powders for three consistencies, we had to make three different sizes of the tubes. However, we thought that it would be much better to make just one tube that can be used for the all three of the consistencies. Therefore, we have made the wooden tool much longer. 
• Also, we thought about putting the rubber around the tube so the height of the tool can be adjusted inside the tube. We found the useful material which is called "O" ring. By doing so, the amount of powders we can get from the tube becomes more accurate
• The photos below show the steps we have done when producing our device. The sketch was drawn with dimensions in full scale, and it was used when we made our product.
