Today we were fabricating the 3D printer top and bottom plates. The outline of each plate was converted into a DXF flat pattern and uploaded into the ShopBot software, so that we could cut out the shape.

While using the software, we failed to realize that the DXF flat pattern was not centred on the sheet of aluminium. This resulted in an attractive “accent chamfer”, as well as the discovery of a little button which centres the pattern.
