After some feedback from professors, a slight modification was made on Prototype 3. The Prototype 4 will follow the previous model’s structure but the alcohol and mixers will be in uniform glass containers (Figure 5). This modification will give the drink mixer a cleaner look. In addition, it was decided that the main structure be made out of wood, with castellated edges or with 3D printed corner brackets to assemble. Available materials on campus are 3 mm thick MDF sheets of 30 x 40 cm dimensions, and PLA for 3D printing.

During this week, the final bill of materials was sent to be approved. Considering the only modification made to Prototype 3 was purely a change in the containers, the components needed for Prototype 4 are the same that were listed before. After receiving approval from our professors it was sent to the department responsible for ordering material. Some trouble was encountered due to the modification of the original file, however after solving these issues the components were ordered and expected to arrive after holidays. The final BOM is included in Appendix 2.
