Assignment 5: 3D Printing
Redbull Can Adapter and Coronavirus Face Mask
Completing a CAD tutorial for a 3D printed object
This week's assignment was to first find a CAD software tutorial and follow it to create a simple 3D model. Since I am using Onshape for this course, I found a tutorial posted by Maker's Muse on Youtube for designing and 3D printing a Redbull drink holder that would be placed in a car seat. Since redbull cans are typically smaller than average cans, they do not fit nicely in a typical car's drink holder and tend to flop around. So, some form of can adapter, that would fit into a car's drink holder, is required to hold the smaller cans in place. Below is an outline of my process for designing a creating an adapter for smaller cans.
- First, I needed the dimensions of a typical car's drink holder and a redbull can. I used the measurements that were used in the tutorial. Using Onshape, I created a sketch on the side plane of the side part that would later be revolved around an axis to create an open cylindrical shape. sketched out what base pieces I would need to design to create a sphere. This shape tapers a bit (i.e. is thicker arond the top than the bottom) in order to account for shape of the car's holder. I first used the line function to randomly draw the shape required (looks like an odd L shape). I then used the dimension tool to change my shape into the dimensions used in the tutorial. See image of sketch with dimensions below. I then locked the 2d sketch to the origin using the coincident tool.
