We wanted a platform that would support the TP roll as it descended, but that would also not interfere with the loading of that roll onto the spindle...

Here is a selection of our iterations of the platform design (in the end, we could not get the platform sturdily affixed enough for us to have confidence in a fully loaded (heavier brand of tissue) run...

This was purely conceptual and was not actually built into our complete structure (we knew it wouldn't "mesh" properly with anything else)...

These were "build-off bases" that would attach to the metal slider (which we chose because of the lower friction and greater structural stability over plastic refrigerator and dresser drawer rollers)...

This was our swiveling platform (that we wanted to have more structural support, since it was made out of fairly soft plastic that bent easily):

These were some temporary mounting ideas...

As you can see, our "projecting process" was highly labor intensive and the constructive iteration is most clearly seen in this component of the Concetta system because we were the least certain about the main design of such a mechanism...We also considered using the same type of gear track as we had for the catch, as well as claws/robotic arms, but we were primarily concerned about weight...To see the platform and other mechanisms in motion, please visit the Action! section.
