Assignment 01: Make a CAD model of your final project
List of content
Background
The requirements for this assignment is to create a CAD model for the final project. Currently i have a very crude version of a radio controller, image below.
Design process
The design process behind creating the controller is that a controller is a box with electronic in it, and joysticks attached to that box. Ideally i want a lid for the box so the electronics are kinda protected and hidden away. The requirements for the lid is that i am able to remove and it needs to be locked in place. Using metal screws in plastic is not a good idea since the plastic takes damage over time and then the screws no longer holds the lid in place. I was given screw holes fittings which needs to be melted into plastic, so first step was to test how these worked.
The screw hole fittings required that the plastic holes had 4mm in diameter. Applying the fittings was easy as all i needed was to use a pointy soldering iron to heat up the fittings and push down into the plastic. The metal reached melting temperatur of plastic almost instantly.
The screw holes in the controller i originaly made was 3mm. This was before i knew the dimensions of the screw hole fittings, so to fix this i used a 4mm drill bit to make space.
The result i ended up with is this:
Future work
The powerplug does actually not fit the hole made for it. So the controller needs to be redesigned. I also forgot to make space for the radio transceiver, so i still have to decide whether to hide it in the box, or attach it on the outside somehow. The electronics are still connected to the breadboard and needs to be rewired into something smaller to fit the box.
