and 3 as well as one of the clear acrylic triangles.

These parts form the kaleidoscope’s eyepiece.

Slide circle 1 just over the ends of the brace

the end notch of one brace piece (Figure

).

Next, set the frame on its end, with circle 1 on

top, and place circle 2 over circle 1, so that the

top surface of circle 2 is flush with the very end of

the six brace pieces. Slip the clear acrylic triangle

into the triangular hole inside circle 2 (Figure

E

).

Finally, lay circle 3 on top of circle 2, and secure

all three circular pieces together with three of the

12mm M3 screws and nuts (Figure

).
