Spice Rack Pull out Remix

Saw Spongybobs spice rack and I liked the concept.

Once I printed it, I felt some improvements could be made.

These were my main issues.
* I did not like the chunkiness of the Rail and the large gap below the Tray.
* I did not like the Rail being square on the front. This allows the corners to be exposed while rotating.
* I found the center pivot location on the Tray crated some installation limitations. The Rack could not be that close to a wall. Guessing 10cm.

Changes
* Extension stop moved to the bottom of the Rail.
* Rail Box Section Removed. Most of the structure elements were incorporated into the Dove Tail section. Including the two taller ribs on the bottom.
* Rounded front of the Rail.
* Moved the pivot in the tray closer to the rear.
* Added a front Trim piece under the Tray. This also doubles for the insertion stop.
* Made a Pivot Pin so you the tray movement would not use screw thread as a bearing surface.

Only made the single layer Tray. Sinc
