Throughout our journey, we faced countless instances of despair and felt that our project was impossible to complete. However, we have to remember that there are always people available to assist us and that we are not alone. The professors, lab seniors, and even our own batchmates gave many ideas and suggestions that aided us in overcoming our obstacles. 

Through this project, we learnt that we are not just innovating a product; we are also entrepreneurs. In promoting a product, it is of vital importance to ensure the convenience of the users. A gentle learning curve is always welcome, especially when the product is supposed to provide a simple solution to a complex problem. 

In Phase 2 (Hardware & Software) of the Development, although there may be a glaring present solution which just required modifications (the Marlin firmware), it would have been an extremely tedious and arduous process. Though we were put off by the idea of it initially, programming from scratch through the utility of test codes turned out to be the more efficient and effective solution.

When we were initially still on the design that required syringes, we had to measure the length of it so as to customise the 3D prints. As we did not have any measuring device, we tried to use a measuring application on an iPhone – which was not accurate at all. As a result, we had many 3D printings of the wrong size and dimensions. We could have saved more plastic used for 3D printing. This is how NOT to do it:
