Yesterday and this morning, Claudia and Vanessa went on shopping trips to buy some extra stuff for our project!

Styrofoam Sawing
The styrofoam cylinder Claudia bought turned out to be just a tad too big to fit into our Embroidery Hoop Mk II. So Claudia and Vanessa laughed away sawing and cutting at the styrofoam, using a vacuum cleaner as well to suck up the loose pieces. The outcome…
Kinda looks like a wedding cake gone wrong…?
The styrofoam became unleveled and we decided to go back to using our old styrofoam base. ^^;
Yarn Feeder Mk V
The pieces that we sent for printing yesterday before we left were done! The backing (that very much looks like cheese/Spongebob) were of the right dimensions for the screws.

Although one of our needle tests didn’t work out so fine, the black one below printed out great. We decided to go with this one. The reason why Vanessa bought the florist wire was so we can make our own needle threader, since we lost the long one that came with the punch needle set. We were able to thread the yarn through the holes using our own makeshift threader just fine! Lifting the piece up to the light, it looks like the thread is better aligned for the needle to stab through as well (centre image, below).
The yarn & needle feeder piece. The main change is the addition of the small hole at the bottom of the needle guide tube, that will aid in better aligning the yarn in the stabbing path of the needle.

Finally, we sawed the acrylic piece into the right shape and size, and used our new epoxy adhesive to glue the three pieces together! We had to wait for a while for it to adhere properly. Finally, we tried mounting it onto our 3D printer. Unfortunately, the screws of the backing piece do not exactly fit onto Main Body, so we used a temporary tape solution to attach it first.

We had a few trial runs, but unfortunately, the yarn was not able to catch fully successfully onto the felt 100% of the time. We wanted to try to maximise this likelihood of success as far as possible.
Revising our Main Body & Yarn Feeder
Since the yarn was not adhering to the felt well, we decided to change our design. The bottom surface of the Yarn Feeder Mk V seemed to be too large and too rough, preventing the yarn from adhering well. We needed to minimise the contact area between the felt and the Yarn Feeder base. So to allow this, we decided to redesign our Main Body and Yarn Feeder. Vanessa went to look up a few designs online such as the one that Disney has used. From there, Vanessa decided that in order to reduce the bottom surface of the Yarn feeder Mk V, one way will be to bring forward the backing for the yarn feeder and merge it together with the Main Body Mk II. From there, we can then 3D print a similar design to Yarn Feeder Mk I and attach it to the support backing that is now merged with the Main Body Ml II. Claudia helped to design and print the new Main Body Mk III back piece in Fusion360, while Carissa designed and printed the new Yarn Feeder Mk VI.
The sketch for the new designs!
Main Body Mk III (back piece!)
This piece would be an overnight print due to its larger size.
Yarn Feeder Mk VI
At the end of the day, we were able to check on our finished Yarn Feeder Mk VI!
Although on the surface it seemed to have printed out fine, the inside tubes were clogged due to the support structures that were printed on the inside. We tried to use sharp pointy objects but only managed to clear the vertical needle guide tube of the filament. The yarn guide tube was more difficult to clear due to the bent portion. Seems like we’ll have to reprint it without supports.
