Limitations

There are a few limiting factors to keep in mind when designing the inner compartments:

1. The center needs to be large enough to house the mechanical/electrical workings
2. There needs to be 8 compartments for 4-days worth of food
3. The compartments need to have a minimal number of nooks for easy cleaning
4.  The design must keep in mind the limitations of the printer
• The printer prefers small pieces to larger ones
• The printer prefers a minimal amount of material used
• The printer cannot print dimensions larger than 12 inches
5. The pieces must completely separate the food compartments from the electrical components
6. The compartments housing the food must be adequately separated from its neighboring compartments.

Combating these limitations:

1 The Center

The servos is the only piece of hardware that will be in the space of the of the centerpiece.
The servo's axis of rotation is not exactly at the center:

From servocity.com

C=1.352"
L=0.174"

So the maximum distance from the centerpiece to the edge is 1.526 inches. This means that the centerpiece's interior needs to be larger than 3.052 inches

2 Eight Compartments

The compartments must allow for multiple days of convenience and care. The entirety of the container can be swept radially from the center by 360 degrees, so the mid-line of each eighth needs to be 45 degrees from the previous.

3 Easy Cleaning

A way to avoid corners made by the meeting of the floor of the container and a vertical ____ is to camber the corners. The assembled piece(s) will slope downward to achieve this effect.

4 Printing limitations

The lab is equipped with a few printers, each with ____ of function. The largest prints a maximum of ______ and it is preferred that the pieces being printed take under __ hours to print and that they don't use under 1 cartridge of material.
