I see there is plenty of miscommunication
1.Tutorials I follow mostly are from Hammerly ceramics and VanTiki on YouTube.
2. The printed figurine is solid. As filler I ment clay around the figurine.
3. What you see on picture is demolded object flip around. I do exactly what you posted on picture Mold Making and Plaster Mixing 101
Well I will let you know if I figure it out. Maybe I do something stupid what I'm not realizing
