What you need for assembly:

• Normal all-purpose glue containing solvents, e.g.

UHU, Evo-Stick Impact, B&Q all-purpose glue. Do

not use water-based all-purpose glue or white

glue, they soften the cardboard, warp it and do not

adhere well to plastic parts and the varnished card-

board surfaces. Solvent-based all-purpose glue

also dries much faster.

• Double sided sticky tape for the plane mirror. Some

solvent based glues can damage its reflective coat-

ing.

• A small piece of sandpaper (medium to fine) to

roughen the edges of the screen to help the glue

stick to the plastic surface. The craft files from As-

troMedia (order No 400.SBF) are also very practical

for this.

• A sharp craft knife, e.g. the AstroMedia craft knife

(order No 401.MES), or a narrow-tipped scalpel to

cut the thin holding tabs of the pre-punched parts.

• A cutting board or mat, made from hardboard,

plastic, or wood. Self-healing cutting mats are ide-

al, as the material re-closes after each cut.

Not absolutely necessary, but helpful:

• For perfectionists: a black and a golden pen to col-

our the white edges of the cardboard.

Tips for successful assembly

The building instructions are divided into 32 small

steps with detailed descriptions. At first glance, this

looks like a lot of text and a lot of steps, but it makes

assembly easier and faster because each step is

small and easier to understand. Please read each

step from the beginning to the end before com-

mencing and allow yourself about 3 hours for the

construction (depending on experience). The more

care you take, the better your camera obscura will

work and look.

Each part has its own name and part number,

consisting of a letter and a number, printed in a

convenient place on the front or back. The letters

denotes the chapter the part belongs to, the num-

bers denote the order of construction. Only remove

the parts from the cardboard as you need them.

The places where something is to be glued are

marked by grey areas. Please note that these glue-

ing areas are usually a bit narrower and shorter

than the part that is to be stuck on. This ensures

that the grey areas will be completely covered. On

each glueing area is a symbol that indicates which

part is to be glued there.

We recommend that you do not tear the parts out

of the cardboard sheet, but cut through the thin

connecting tabs with a knife to make sure that the

edges are completely smooth.

All folding lines are prepared by groves or perfo-

rations. If they are to be bent 'forwards', you have to

fold them towards you when looking at the printed

side of the part. If they are to be bent 'backwards',

you need to fold them away from you. You get a

straighter fold if you position the folding line over a

sharp edge.

A. The Front Wall and the Side Walls

The walls, base, and viewing window of the camera obscu-

ra form a cube-shaped housing measuring 190 x 190 x 190

mm. Walls and base are made of strong cardboard, the oth-

er parts with visible folded edges are made of more flexible

cardboard.
