+1 0 -1 Thank you. Looking well and making some calculations, 3D Hub Marvin volume 2.5 cm is 2.4 cm3, 5 cm is 14 cm3 and 10 cm is 92 cm3. Neither Cura , UP Plus or my Catalyst ( stratasys ) gives me that Volumes for Marvin and of course Catalyst gives me a higher value because it always create support. But any way it gives me a pretty higher close value. I took a look well at the info when you set price for a specific filament and it is calculated with a 25% infill and 0.8 wall thickness.
