Startrite 275 dust extract outlet

I own a Startrite 275 table saw and for a few years, my old method was to sweep up the chips from the sloped outlet. this became annoying over time so I decided to design and print a new outlet that I can connect to my dust extractor.
The internal edge of the door has a steel lip on the inside that can be used at a connector, so I designed a Z top hat section to hook over the existing door edge (no fixings or connectors etc). I also designed it to have several 8mm x 2mm magnets (rounded size)
