From the concept of lightness and natural, paper may suggest the possibility to create that. a 2D paper cannot have spacial element there for fold out some space is needed. by folding Rigid Origami is a topic that human investigate math and physic. Which i started from this way.
Roof:
As in the grasshopper attempt of Rigid Origami, i try making prototype.
To do so i try learning mountain fold and valley fold from a random paper. I trace the "peck" and find out they do have some pattern of geometry but not so obvious. However triangle is a possible choice to recreate the sense of space with its lightness.
Just paper and masking type to make the designed form and it successfully back to flat or 2D. (staple boxes are just for temporary support.)
I do think of re create the form into on piece and laser cut it . However i want to give the roof structure more lightness and light can penetrate through the roof so i have keep using the same method when i build the prototype. Using balsa as in represent the timber structure of the roof. It is a reasonable material that give the lightness and it is natural.
In some parts need to angle the balsa in order to match the angle of the flow. 1st method i use is just cut by knife and it is so dangerous and risky to cut the fingers. So i try using the sand paper with block to sand out the angle i want.
The only problem is the installation of LED light at the ceiling. They need to carefully located and with the cables detour in order not to block the light going through the gaps but not create shadow at the center of each piece of balsa.
Remove the plastic protection off the cable. Sometime do feels like i am doing surgery ...
In this model i had use the 3mm LED on the right (left is 5mm normal LED) to minimize the impact from the LED circuit.
Roof socket:
Another problem is the different system of circuit. I want to separate the ceiling and floor circuit and the roof is removable for me to take picture easily. Therefore a tiny socket is needed.
3D printed 2mm (W) X 1mm (H) X 3mm (D) sockets.
After Assembly all the parts and as show on the imagine above the ceiling light turned off but the floor still on when the socket is disconnected.
Central structure:
In Other to lift out the roof structure, the central core need to be strong enough. Suggested using semi transparent concrete and in this model i have use semi transparent PLA to 3D print the designed tree trunk like core structure in Solidwork.
Central structure stair case:
Lase cut the acrylic steps.
Apply UHU carefully could stick two acrylic clearly. I just wounder it is better to stick two pieces not in the same face, i.e. top face stick to the bottom face of other piece. Looks like there are less resistance and stick even better in this way.
