Dome

MIDDLE - LEFT - RIGHT (what a nice mantra)

the overview

Cut and drill.. 500 holes

Spraypaint

Some finished struts

Painting done

Construction

Done!

Cosy

Deconstruction (~10 minute with 5 guys)

Preparation

You need:

• 250 bars (get 270+ to have some spareparts) the inner parts of slatted frames for beds work great
• 91 M6 screws (length: 80 mm)
• 91 Wing nuts
• 182 Washers (the bigger the better)
• Spray paint (RED,GREEN,BLUE,ORANGE)

Cut them in 5 different lengths.

Type	Color	Pcs.	Length
A	ORANGE	30	60cm
B	RAINBOW	90	70cm
D	GREEN	70	74.2cm
E	BLUE	30	77cm
F	RED	30	70.8cm

Drill a hole 2cm from the border in the middle of the struts ends.

Assembly

Start with 5 pcs type A struts (orange) Connect them like this: WASHER, SCREW, 5 BARS (A),WASHER,WING NUT, dont over tighten yet

You successfully put together the middle structure that will be on the center top of the dome.

Now from the end of these connect 5 type B struts. The magic formular is:

MIDDLE - LEFT - RIGHT

• MIDDLE (A) outermost layer
• LEFT (B) middle layer
• RIGHT(B) innermost layer

and thats how you go on according to the diagram above.

This is true for the whole assembly.

Take a corner of a triangle, consider that "middle" and connect first left and then right to it.

Notes

There are 5 types of triangles:

Type	Count	MEASUREMENTS (center connectior -> center connector)	MEASUREMENNTS FOR CUTOUT
AAB	35	60x60x70	52x52x62
BBB	35	70x70x70	62x62x62
BDF	65	70 x 74.2 x 70.8	61 x 66 x 63
DDE	25	74.2 x 74.2 x 77	66 x 66 x 69
EEE	5	77 x 77 x 77	69 x 69 x 69
