Final model

Things to remember when constructing my final model:
- start cuts at a minimum and work my way out
- remember to clearly analyse which angle is preventing perfect assembly before cutting anything
- consider where tapers will effect other angles.
- always snap blades off to prevent cutting too deep into cardboard.
and...
only cut the cardboard and not your finger!

Xanita 1:1 mock up

Here are some images of my Xanita mock up. This was alot more tedious than expected, but i learnt several lessons for my final 1:1.

With the final plains folding on top of the whole chair and slotting in to hold the whole thing together, it is important they are the right length....obviously didn't happen here as they are not lying flat upon the supporting cardboard. Half a centimetre of each side would have cured this problem.
While cutting the chair I came to conclusions about which angles were preventing it from sitting accurately and sometimes drew the wrong conclusions, this would be an example: I thought the angle on the bottom of this plain was not large enough when in fact it was one relating to the taper of my chair. As a result, there is a gap...noooooo
Below is a perfect example of something that was disregarded all together. As the other side of this plain is tapered, this end also tapers..derrr. The end of this flap also needs to be cut on an angle as it meets an angled surface.

Also note the gaffa tape down the side..wooops, cut too deep.

Flat pack

Here is my final flat pack before constructing the chair out of xanita....let's hope it works!

Measurements and the lengths of card required will obviously always change with each attempt as each fold will require a certain amount of extra length. Because of this, it is vital to not over cut any lengths and to start small and work my way up.

Angle testing

Here are some tests i did with papaer, card and xanita to allow me to become familiar with the material, angles, cutting and tension.

Findings:
- alot more material needs to be cut out than i originally thought for allowing angles to work.
- tabbed locking system very strong

Solidworks

This solidworks drawing was done to work out other lengths in relation to the angle. After concstructing out of card however, it came to my attention that I forgot to take the taper into consideration; therefore requiring the 7.13 angle on the flat plan to actually be doubled....oopsy

Finding correct angles

This was a quick working out of the angle in which my chair would taper from viewing it side on.

This suggested that my angle would be 7.13 degrees.

Final Design | 1:1 mock up

This was my first attempt of a 1:1 mock up using three layers of traditional corrigated cardboard.
This design has proven strong enough to hold the required weight but lacks in a neat execution. For further development i need to focus on obtaining the correct angles for the chair to work aesthetically aswell as functionally.

Sketches - Developing final design

Through these sketches I explored the idea of a tapered triangle stool. I was then adding angles within that form but struggled to find a way for it to be sturdy/intelock.
This lead to me to simplify it down to a tapered cube. With elements from last years examples that I liked, I formed a first draft of my final design.
