Short-run injection molding through a service bureau such as Protomold
was determined to cost approximately \$2,500 for tooling and a fixed
! lot of 25 parts, and between \$3 to \$10 per additional part (depending

- \section{Mica Mote Chassis}
-
- Early on we identified the following design objectives in a mounting chassis:
- \begin{itemize}
- \item Tool-less; requires only hands and possibly a coin to
- open, disassemble, reassemble (rapid and simple)
- \item Separation of modular components: sensing, power, mote, antennas
- \item Wiring harness to separate power connection
- \item battery cage design to accommodate different battery candidates
- \item Supports mounting by: screw, strap, zip-tie, velcro, magnet, hook, or similar
- technology.
- \item Injection moldable for low-cost high-volume production
- \end{itemize}
-
-
- \subsection{Design for Assembly}
-
-
- >>Boothroyd references
-
- -mounting mote onto chassis; supporting edge connectors
-
- -using wiring harness to connect power to mote
-
- -pyramid assembly
-
- -using standoffs as thumbnuts
-
- -chamfers on the battery clip
-
-
- \subsection{Design for Injection Molding}
-
- -straight-pull design
-
- -avoiding undercuts
-
- -constant wall thickness to avoid shrinkage
-
- -shelled design
-
- -strapping slots ribbed for rigidity
