Angel Mold

thingiverse

My wife asked me for a mold to make an angel out of concrete for our garden. She likes the Angel by maggiman2001 from Thingiverse so much that she wants to replicate it. https://www.thingiverse.com/thing:1319278 I used MS 3D Builder, creating a cube around the angel and then subtracting the angel itself. I divided the block, but at this point, the mold is pretty useless. I was thinking about breaking or destroying the mold anyway, or maybe it could work with flexible filament, which I don't have to test right now. I'm really new to 3D printing and modeling. I got my Ender 3 just two weeks ago, so please bear with me! I'm still learning, so if you have any constructive tips on how to improve this mold, I'd be grateful. (Currently printing a 50% prototype) The original angel can print without supports, so I guess the mold doesn't need them either?
