Introduction: How to Make Fab Table

Fab Table is a new type of table.
You can record and project handworks on a table which iPhone or iPad is installed.
You put your iPad/iPhone on the top when you record your handworks.
Movie will appear 1:1 scale on the table.
By copying the handworks projected on the table, you can share technologies on a very high level,
Fab Table can upload movies then and there, so you can send your handwork technology to the world or learn technologies from all around the world right in front of you.
This Instructable will teach you how to make one.

Step 1: Download CAD File

For ones who can use Grasshopper(Rhinoceros), download "fab_table.zip"(there is a Rhino file and GH file in it, choose the one you need).
Caution: this Grasshopper data is version 5.0.
Hole for acrylic sheet on the top table is not open in GH data. You need to open it using boolean difference and etc.

For ones who cannot use Grasshopper(Rhinoceros), download "fab_table_shopbot.zip".
You can directly cut this data out using Shopbot or other CNC milling machine.
Dimensions for table is
top table(table dimension and height): 480mm x 600mm x 500mm
bottom table: 480mm x 600mm x 740mm
acrylic sheet: 320 x 456mm x 6mm
height of top and bottom piled up: 1228mm
minimum height of pole: 500mm

Projector Attachment(download "projector_attachment.zip", it includes stl and GH file; choose the one you need)
Caution: The hole for the screw is made based on JIS standard. Edit it so that it fits your country's standard.
Each parts of projector attachment is not unified. You need to unify it using boolean union.

Step 2: Prepare Data

For people who downloaded GH file, please open a hole on the top table for the acrylic sheet.
You may adjust your hole depending on the size of the acrylic sheet you have,
but make sure you offset the lower layer hole 5mm inwards for each side.

Step 3: Cut It Out

Cut it out using Shopbot or other CNC milling machine you have.
The wood we used is plywood panel with dimensions 910mm x 1820mm x 12mm(we used three pieces).
Print out the projector attachment using 3D printer.

Step 4: File Every Parts

I prefer you to file your parts before building it up; you don’t want any rough edges on your desk.

Step 5: Assemble(1-lower Table)

Assemble each parts. Follow the picture above.
Be careful for the direction of the two base parts. The two should be organized in the same direction as in the eighth and nineth picture.

Step 6: Assemble(2-upper Table)

Assemble each parts. Follow the picture above.
Be careful for the direction of the parts; this time, the upper part of the hollow should come to the side which the two base parts has a low end at the corner. See the third picture.

Step 7: Assemble(3-finish)

Pile up the two table and put on the acrylic sheet. Handle it with care. 
Put the projector attachment on the pole, then the projector.

Paint it and/or attach a LED lamp by optional, and you are finished!

Step 8: How to Adjust the Projector

You may adjust the projector in the following steps:
1. Put your iPhone/iPad on the acrylic sheet and record the table. Mark the recordable area on the table using masking tape.
You should put some object on the table while recording.
2. Project the recorded video, and make sure that the scale of the object projected matches the size of the real one.
