Idea: A movable „arm“ that allows going back, forth, left and right (movement in x and y direction) <br>with  a changeable „nose“.<br> Make the printers inner movements visible outside of the casing.<br><br>

[[File:cutting1.jpg]]<br>

Cutting the „arm“ pieces out of Kappafix (accessible, easy to work with, strong enaugh and flexible<br> at the same time).<br> Gluing them together (sandwiching) for a better stability. <br><br>

[[File:cutting2.jpg]]<br>

The upper arm needs a „Slider“ - Something that is glued to one part of the arm holding the other (movable)<br> part of it in place. <br> It is important that the „Slider“ is not too tight nor too lose. <br> It should not be too hard to push the flexible part in and it should not have too much space to the <br>left and right at the same time. <br><br>

[[File:cutting3.jpg]]<br>

The „Slider“ made of papercard glued to the longer side of the upper arm.<br><br>

[[File:ReexWheel1.jpg]]<br>

The lower (static) arm did not move back and forth - the pressure from the wheels of the printer <br>was too low.<br> Another single wheel had to be installed that allows the back wheels to apply more pressure<br> on the arm.<br> The same thing has been done in the front later on.<br><br>

[[File:3erWheel.jpg]]<br>

How can the „joint“ of the two arms move to any x/y direction?<br> It needs wheels that are like rolling spheres.<br> This prblem has been solved with wheels from the hardware store:<br> they contain axle bearings that allow them to circle around their own case. <br>Three of these wheels are enough for a stable platform.<br><br>
