3D Designer for Easter Bath Bomb Press

I am seeking a skilled 3D designer to create an STL file for a bath bomb press in the shape of a smooth Easter egg. The design should function similarly to a waffle/toastie sandwich maker—two halves that press together to form a clean, consistent egg shape.
Similar to the tree that has been uploaded.

Requirements:
- Smooth, symmetrical egg cavity (no texture or patterning required).
- Two-part press design (hinge is required).
- Easy-to-use mechanism for pressing bath bomb mixture evenly.
- Consideration for venting/air release to ensure proper compaction.
- STL file ready for 3D printing (preferably optimized for PLA or PETG).
- Durable design with ergonomic tabs or handles for pressing.
- Complete ownership of file due to commercial licence.

Deliverables:
- STL file of the complete press.
- Notes on recommended print settings (orientation, layer height, infill, supports).

Ideal Candidate:
- Experience designing molds or presses for 3D printing.
- Strong understanding of tolerances and fit for functional prints.
- Ability to provide revisions after test printing.

Goal:
A reliable, easy-to-use bath bomb press that produces smooth Easter egg shapes for seasonal products.
