Fusion model:
  the model needs cleanup and to make explicit which parts are reprensenting
  mechanical parts, which parts are to be 3 D printed
  and which parts are to be laser cut.
 
 3 D Printed:
 I sent 2 jobs to 3 D print with ABS material to the Stratasys
 machine. Each job was ~20 hours. The resolution is very good in the finished
 parts. 
 
 Laser Cut: 
 I used Delrin 6mm thick with epilog 120watts. The settings were 20% speed
 100% power, 500 frequency. 4 passes each piece. The material gets heated
 and need to take turns in cutting each piece. The fumes are very toxic. I will
 try to replace some parts with acrylic.
