For this assignment, we must create a virtual object by intersecting 2 or 3 three dimensional geometric primitives (e.g.three-dimensional geometric primitives (e.g., three-dimensional box, cone, cylinder, etc.) at a non-perpendicular angle.

Scale your model to your final model's digital and physical craft fit snugly in a 300 mm^3 box.

Unwrap your model into a flat plane.

Print, cut, then reassemble your model out of card stock provided. You will be graded on the quality of the digital and physical craft of your final model.

For inspiration, I looked at diamond rings first, but I found it difficult to present the ring with the paper model. I really like the shape of the diamond. then I looked at the present boxing and I want to mix the features of the two into my paper model. 

Again, similar to assignment 1, learning entirely new software is a disaster for me. After watching a few tutorials on YouTube and Hans' lecture recording, I learned some basic skills for using Rhino.

Then I moved on to my shape on Rhino. I had a pentagon corn inserted on top of a square box. I got the idea for the previous section.

To ensure my model fits in a 300x300 box, I have created a 300x300 box and rescaled it, making sure it fits. However, the model is within the 300x300 cube on the respective page show on the respective page where the model is within the 300x300 cube I exploded the 300x300 cube and deleted three sides.

I then flat the 3D model using the command UnRoll SURF with labels. However, it turns out that it does not connect to individual panels. I asked my tutor, Fiona, about this, and she told me it was all right, but this foreshadowed problems with assembling the steps in the future.

I start printing out my unrolled surfaces. I got printing issues at the beginning because I could not top up, but I soon fixed this by using a different bank card and finally started producing work. To print, I ungrouped the unrolled surfaces and created an A3-size rectangle to make sure the panels fit. but the actual size was very large for trails and iterations. so I reduced the scale of the surfaces by 0.8 just for time consuming and saving paper. Then I attached the printing paper on the prototype paper with masking tape, ensuring they were fixed. I start cutting with a craft knife and metal rule for safety issues.

After the panels were cut off, I labeled each side so I did not get mixed up when gluing.

I did not add glue tabs for some edges on Rhino. Instead, I added them in the cutting stage just for trailing purposes from my assembling ideas.

This video shows the method I use to fold the glue tabs' lines. However, I found that this was inaccurate enough, leading to messy corners and edges. I saw another method: scab a line on top while the print is on with a metal rule and pen; this led to much cleaner edges.

I came out with my first iteration. Unfortunately, I got my scale wrong when printing, so the pentagon prism did not fit onto the cube and left a huge gap. Also, when applying the liquid glue adhesive, I used too much glue, so the adhesive glue went all over the model. The most important problem is the glue tab. I forgot to add the glue tab when cutting, so I have to use masking tape to put them together, which describes the aesthetic.

For my second prototype. We ran out of colored cardboard, so I used a different type of prototype paper provided. Improve from the previous version, I corrected the scale when printing. As well as start trialing for the glue tabs. Glue tabs worked well, but I missed one on the bottom. In prototype 2, there is still a problem with the adhesives. I cannot even put the glue on the tabs, so it wets the paper to make it scumble. Also, with assembling issues, gaps between surfaces exist, which is what I do not want to see. 

For prototype 3, I improved the adhesive application. I used scrap paper as a brush to smooth the glue so it dries quicker and does not wet the paper. Unfortunately, I missed out on a glue tab on the top again somehow in the trailing process. There is a large improvement in the quality of the assembled model, but gaps in the Pentagon prism still exist. Also using separated panels led to inconvenience and aesthetic issues mentioned earlier in the 3-D modeling process. And now, I am confident enough to move on to the final model.

For my final model, I made changes to the printouts. I connected the cube's edges, which led to less cutting, gluing, and more clean edges. After trailing with glue tabs, I have added them all onto the Rhino to take advantage of them. Unlike my prototypes, I have to ensure that the actual size is printed, so I have combined four A-3 printing papers; this is a disadvantage for putting panels together. In the cutting process, this advantage has enlarged. When putting an A-3 rectangle box together, the gaps and unmatched edges led to difficulty when cutting. Sooner, I solved this problem by lining them up with the long metal ruler. To solve the adhesive issue above, I used the 'brush' I made and also waited until the glue was dry to put on the next piece.

-Photo showing scale (comparing with power bank in FabLab)

My final model turned out well, with mostly clean edges.

 Things to improve

- cutting with more care

-when printing, the A-3 rectangle box I use for reference needs to be more accurately

Placed and compacted.

-The top Pentagon needs to be perfectly reassembled and is left with gaps.

This assignment taught me skills using Rhino and how to unroll your 3-D shape. When Crafting the model, I learned to be careful and accurate with cutting and gluing; for example, cut slowly with a metal rule and set the ruler to the right place before cutting, and hold the glued pieces in place for a few minutes to make sure it is fixed in place. Most importantly, I learned to solve critical values when improving my final model from my prototypes. In making models in the future, I need to be more accurate and patient to produce my best work and show my potential.
