Printed many of these already on my Prusa MK3S+ and worked really well and with different Filament and Paper colours you can create some really cool Birthday Cards.
In case you wonder why its printed the wrong way round: I use the smooth PEI sheet on my Prusa and it just gives a really nice surface at the end. In case you dont have a smooth sheet, turn the modle around and enable ironing to get a better looking surface.
