This model is awesome!
I printed it on my Creality CR-10 at 30% scale, it is 12.6cm high.
Tilted 4° in Cura, 0.1mm layer, marble PLA from Grossiste3D. I've played with the setting in order to avoid support behind the pillars ;-)
86° overhang angle for support and 15% density. Along with the scale, no support was inserted there.
210°C hotend, 60°C bed, 1.2mm walls & top & bottoms. 15% infill. 60mm/s print speed. Brim to make sure the bottom support will remain on the bed!
So the bells are printed - not yet removed their supports... I'll try with a hot wire.
The result is very nice.
