I've created this sculpture for a "TED talk" like gathering with the subject of "The history of work". It turned out nicely so I thought to share it.
It is quite challenging to print though because you do need great cooling.
It can be done without supports if you've got great cooling on the print. I've got the "bullseye cooling duct" on my ender 3 and with that you can get a pretty clean result. I have to admid that it doesn't look as clean underneath it's head but it doesn't bother me. If you're not confident in the cooling of your printer or you want a cleaner result underneath it's head, you might want to use supports. I allways try to avoid it though.
I looked at the road work sign from The Netherlands for inspiration and just started sculpting in the program "Sculprtis". To create a straight stick I used 3D Builder to combine the model with a cylinder.
