Laser Cutting

For Laser cutting I used 5mm thick acrylic black and white sheet.
The parameters i used to cut the acrylic was-
Power-90-95% Speed-20mm/s

3D printing

For 3D printing I used tough PLA material and slice using makerBot Desktop
The instruction are given in Week 6 Assignment
I printed it using 10% infill with no supports and Rafts on. The rest were the default settings used.

System Integration and wire Management

This was one of the main feature that Neil focussed on as the wires coming out can be fragile and good system needs a good system integartion and it should be robust a bit so that it does not wear tear off in one or two use or in carrying.
For this I got some spiral springs to which I tied all the speaker wires and the enclosure that I laser cut I gave the slots onthe sides acuurately to the size of my coonectors so that it can just fit in and all the messy wiring issues can be improved. I added some masking tape on the IC's just to be sure that there is no chance of Short circuit.

Used some plastic springs and heat Shrings and Tie knots to clean up the wiring
