minimal fish 3d model

Create a manufacturable 3D master model for plaster mold making for ceramic slip casting. Design a minimal fish as a positive master pattern inside a simple formwork box. This model will be used to cast a plaster mold, and that plaster mold will later be used for slip casting a ceramic fish. Fish design: - minimalist fish - simple body silhouette - simple tail - simple fins - no scales - no facial details - no small decorative elements - smooth surfaces only Geometry requirements: - flat underside - slightly domed top surface - rounded edges - no undercuts - demolding-friendly - light draft angles on all vertical or near-vertical surfaces - structurally strong fins, not thin or fragile - suitable for 3D printing and mold making - optimized for easy plaster release and clean ceramic reproduction Mold setup: - include an integrated rectangular formwork / casting box around the fish - fish centered in the box - consistent wall height around the fish - flat outer base - enough margin b
