Tiny print job help

Hi. I use an SL1s and am trying to print an HO scale bicycle https://www.thingiverse.com/thing:3886096. I know it's possible because Josef Prusa says so: https://x.com/josefprusa/status/1176473042098298881?s=20 , but here's the problem I'm having. Supports! I can get the bike to print lovely, but with so many supports they're impossible to remove. I tried making the supports 0.2mm which helped, but there are just too many of them and they fuse together to impinge on the print. I tried reducing those supports to 10%, and the model falls off the build plate. If anyone has any ideas as to how to print this model I would love to hear them. I would probably have left it by now if it hadn't been for that darned Prusa post! Help, anyone? 🖐️

OK, *that* is a challenging print.  I would print it upside down (and perhaps modify the handlebars and saddle to help) - it should need less support that way but resin doesn't bridge like extruded filament - it would probably be easier (though incredibly fragile) with a sintered powder printer.

I have seen both a bicycle and a sack-truck printed for a layout but both were modelled leaning against a wall and printed with it so requiring minimal support.  Sorry, I don't have files.

Cheerio,
