New: Need help understanding supports on this print
I am in my first week of 3D printing, and wanted to try this sponge holder:
https://makerworld.com/en/models/1289902-kitchen-sink-sponge-holder
I opened the .3MF in Prusa Slicer, and of course it will print standing up on end, with no support for the sponge drip lip that hangs over the sink edge. So Prusa Slicer warns about stability and suggest turning on supports. I have never read about how to use supports for a print. Is it a different type of filament that you load, or is there some training video someone can share? Looking to learn how to best print this item.
Thanks,
Neal
In PrusaSlicer, in the pane on the right, just below the printer and filament selection boxes is the option to enable supports... Simple supports are just a flimsy structure printed simultaneously from the same filament, break it off and discard. More sophisticated ones for use with expensive filaments or when surface finish matters do use different filaments and require a multimaterial printer.
This print appears to be a reworking of an old design concept (I don't have a Makerworld account so I can't download it) and while it is not well designed for 3D printing it should be printable — it seems to have mimicked an injection moulded product. There are lots of variants of this type of holder/drainer on Printables and Thingiverse, a quick search found this one, a few years older, which is expressly designed for easy 3D printing without supports... Caveat: I have not tried to print it.

... and there are many others found in a simple search.
Cheerio,
