The Cone is 100100150mm tall. It can be y oust for game or sports. there is 4 holes for Nails or pegs to kip et from toppling or get blown away.
Cones_01 is probably impossible to print without support. I hope that Cones_02 is somewhat possible to print without.
I will recommend that the layer height is 0.10 too minimize overhang.
the best filament will bee flexible, such as PETG or Nylon.
