This week I was mostly focused on making the computer aided design (CAD) for the structure of our gantry. We are using an existing gantry design (https://www.instructables.com/4xiDraw/), but we need to create our own structure design so that our gantry is portable and has the capability to raise and lower.
Shown below is the existing gantry.
From our original BOM from last week, I created the below preliminary model.
However, upon updating our BOM during the middle of the week with extra materials that we forgot, we realized that we were over budget and opted to remove the wheels from our original design for reasons outlined in the Team Status Report for 9/27. This led us to our current design shown below.
Looking forward to next week, I look to gain feedback on the structure design during our Design Presentation and incorporate it into the next and final version of the CAD model. Then when the CAD is finalized I look to order the parts and start 3D printing gantry parts and cutting the ordered parts to size.
