## Mass check of DPM:
## From MEL: Housing mass of 0.19kg = 190 g
## Volume of aluminum housing in this model:
## V_outer= [11.86+(2*0.15875)]*[13.45+(2*0.15875)]*[13.625+(2*0.15875)]
## = 2,337.57 cm^3
## V_inner = [11.86]*[13.45]*[13.625]
## =2,173.41
## V_total = V_outer-V_inner
## = 164.16 cm^3
## Resulting mass for an aluminum alloy housing (rho = 2.6989):
## M = 2.6989 g/cm^3 * 161.16 cm^3 = 434.95 g [TOO HIGH]
#
## Tweak aluminum shell thickness until desired mas is reached:
## Setting thickness to 0.05cm gives mass of 136.72 g.
#
## Add in the bracket. Set thickness so that total masses add to 190g (about 0.11cm)
## M_bracket = [14.69cm*11.946cm*0.11cm] * 2.6969 g/cm^3 = 52.1g
#
## Resulting DPM housing mass: 136.72g+52.1g = 188.82g
## Place the organic shape inside the mother volume
