Project 7 Submission : Paper craft Objects: First Prototype

I designed a guitar as my object and made a prototype with card stock paper. Here are my planar figure to start with.

From top left in clock order, the first two planar figure for guitar body, third, fourth is for the guitar neck with third piece of the guitar body at the corner with 'B'. The last board has guitar head and all the other components. And here I noticed that some of the parts that is on the last board should be placed on the guitar neck board since they are not the same color as guitar head and some parts. The parts are octagons with long tail with smooth surfaces on the top right part of the board, and octagons with curvy tail which is located in the middle of the paper.

★ Problems found

1. Size and thickness of some object

Considering the completed prototypes size and the material used, these parts were too small to craft. The wings couldn't have enough glue on them and that didn't allowed them to hold the other side as expected. So in the future, the size needs to be exaggerated or the shape has to be changed. In the process today, the shapes on the right were changed into flat shape, not possessing any height. The shape on the left, also has a problem making clean outer lines, due to its size and material, so I am considering changing it into a octagonal column, which will not harm the design of the final product.

And as mentioned above, some of the machine pieces were to small to craft. It won't bent on the sport that was designated because they are to small for the thickness of the paper material, which ruined its shape. And the wings were to small to hold glue on it and the other sides wouldn't attached with them.

2. Design failure.

 

The neck sits on the lighter colored part of the body, which doesn't have the strongest support, so they couldn't connected strongly each other. I think I can consider closing the guitar body in other side of the body, so that this additional part will have better support. Or, I can attach additional planar on the body where it connected with neck, which could be attached inside of the neck. And this will require new design for the neck as well, since it will need different way to close this shape. Additionally, I think maybe shortening the neck will help this situation as well, since it will allow less weight of the neck piece. However, it might also harm the intention of baring original proportion of the object.

This piece was lack of surface to close this surface, probably caused from launching wings on the planar surfaces. So the design need to be changed so that it can hold additional planar. 

Instead of having wings on each end of the side walls, I adopted hexagonal shapes on ends of one of the side walls, hoping that it will hold the top and bottom of the column more strongly, but at the same time, since the other sidewalls were not anchored, it was hard to maintain shape. So I think I can adopt a couple of additional wings on one of the side walls so that it can maintain better shape.

When combining all the body pieces, I found additional wing that is not necessary to connect each pieces. This was fixed by cutting one of the wing off.

★ Final thought

I think the adjustment in size will be needed generally, especially for small pieces that couldn't be crafted with the presented materials. I think I can try to adopt bigger size of the paper when printing which will allow bigger space, in result, bigger pieces for craft. Or other options I can consider to solve this problem is exaggerating small pieces, as I mentioned earlier. Some adjustment on design is also necessary for better hold of the shape. This will be practiced on small head machine pieces, bridge pieces and button pieces. But other than that, I think body, neck, head part worked out well considering its paper material.
