In regards to the construction of the communication, I have calculated a current budget estimate and layouts to best utilize our materials on the CNC router. I will address the budget first. The design is currently based on an approximately 30" wide structure composed of masonite ribs and foam. The masonite ribs would be 1 sheet thick or 1/4" and 3 sheets thick on the exterior ribs. The foam would be layered in increments of 5 between the ribs for a total of 3 3/4" thick. The figures would be slightly different depending on whether foam was inserted inbetween the masonite on the exterior ribs for more support. In additional, costs can be cut in half if joints are created to allow more efficient use of the materials.

Current budget with 3 sheets of masonite on either side and no rib joints:
13 sheets of masonite x $8.99 per sheet = $116.87
35 sheets of foam x $11.34 per sheet = $396.90
Estimate of glue = $50
Clear coating for foam = about $50
Dowel for hinge = $2
Side panels of acrylite acrylic- 2 48" x 48" x 1/4" sheets x $75.60 = $151.20
(best option based on research by Nicole- 1/2" are double the cost of 1/4" sheets)
TOTAL COST for Option 1 = $766.97

Current budget with 3 sheets of masonite on either side and two rib joints to allow two ribs per sheet:
10 sheets of masonite x $8.99 = $89.90
13 sheets of foam x $11.34 per sheet = $147. 42
Estimate of glue = $50
Clear coating for foam = about $50
Dowel for hinge = $2
Side panels of acrylite acrylic- 2 48" x 48" x 1/4" sheets x $75.60 = $151.20
(best option based on research by Nicole- 1/2" are double the cost of 1/4" sheets)
TOTAL COST for Option 2 = $490.52

Assuming we use option 2, $490.52 - $250 from school = $240.52 additional cost

$240.52 / 10 students = about $25 per student left to pay minus additional money from professor
