Schott-bottle–compatible funnel-base for Anycubic Photon Mono resin vat

I pour used resin into amber Schott bottles and not back into the bottle, so I need to adapt the funnel base —the filter and the holder are the same (see original).

A Schott bottle is a standard-size borosilicate bottle, so can be autoclaved, which I am obviously not going to do... it is standard labware item —mine are not Duran and off Amazon (https://www.amazon.co.uk/dp/B0B7B95ZBF), but in a lab you'd get it from Fisher or Sigma, basically I am using them out of familiarity.

The original funnel this goes with is a bit tight for the resin vat —this is for the default version, so if the former were scaled this would need to be scaled too.

(Please ignore the filament used: I used an old rainbow filament for ugly prints)
