Week 4 - Sick 3D Printing or Sick, 3D Printing... Also soldering

This week Fabio got sick, so Liam had to finish the 3D model to get it printed on time. In the end it took around 6 hours to print, but the result was a durable, lightweight case that fit almost all dimensions of the components perfectly. However there was one error in that the hole for the USB port on the 3D model was positioned incorrectly due to an error made when reading measurements off a diagram of the Arduino Uno. This was corrected by cutting a chunk out of the case on one side of the hole and hot glueing it to the other to move the hole along.

The 3D print in progress

While the case was printing Liam also soldered the cables for the rangefinder and laser modules, as well as the shield board and gyro and accelerometer module.



Afterwards the parts were assembled together to produce the complete prototype.
