I designed this 3 piece assembly in order to drain resin from the entire vat (thanks to how large the funnel is) into a resin bottle, without the need for a stand. The funnel screws directly into an Anycubic standard resin bottle (although I imagine it will fit most resin bottles). I then place a paint filter, and place the vat holder into the funnel. I also would recommend printing the bottle holder and screwing it into a flat surface ( I used a sheet of plastic so that I can move it anytime). The added stability helps to prevent the bottle from accidentally tipping over. I included screenshots of how I oriented each part in prusa slicer.
Edit: The Anycubic resin bottles now seem to be a slightly different inner diameter, I added an adapter piece to compensate for that
