tension sensing roller 3d models

I did not try to 3d print everything in plastic if metal or wood made more sense and was faster/stronger/easier and not cost prohibitive.  3D Printing is mostly used for the connections and exact positioning of tubing.Everything here is my own design...

The air is thick with tension as the inventor waits for some sign, no matter how faint, that R2D2 still exists. Time ticks by, each passing moment a potential eternity for the inventor, who sees himself reflected in R2D2's vacant gaze. His thoughts...

The curves and lines that comprise this diagram are perfectly mirrored on either side of a central axis, creating an almost surreal sense of balance and harmony. This symmetry is not merely aesthetic; it has profound implications for the underlying...

You also loose the light and temperature sensing. It's not impossible to add this, but it seems to require compiling the code yourself, if you want to add more complex things. It does have support for buttons and potentiometers, but I have not tested...
