Turn4views

This is an original panel that can show 4 different pictures by turning the knob


the whole needs:

3x female end + 3x male end + 3x square tube 20x20 + 2x side hood + 1x of each other part

the 3 axes are made of iron wire (3mm), the assembly is glued
the upper part can remain removable (not glued) to access the mechanisms

(Square tubes 20x20x110mm are better in aluminum)

for fill the panel with pictures:
stick the first picture in the window on the three tubes, and cut the image twice with a razor blade passing between each square tube. Turn the knob by one step and start again with another image. Do the same for the other two pictures.
