3D Concrete Lamp Molds Design

I'm seeking a skilled 3D model designer to create 2 3D printer molds for concrete outdoor garden lamps (35cm high x 16cm wide & 60cm high x 16cm wide). I already have the 3ds .max file with the desired concrete outputs.

Requirements:
- Experience in 3D modeling for concrete applications
- Designs must be suitable for 3D printing
- Smooth surface design
- External frame required for stability

Ideal Skills:
- Mold design principles for concrete
- Attention to detail
- 3D printing technology expertise

Please share your portfolio with previous mold designs.
