Biocomposite 3D Printable Cake Box

I’m looking for a detailed 3D model of a rum-cake presentation box that I can print on my own machine using a bio-based composite filament. The focus is entirely on 3D printing, so the file you deliver must be optimized for that purpose: clean geometry, watertight, and ready to slice without excessive supports.

Here’s what I need the freelancer to cover:

• Overall concept: a box (base + lid) that protects and showcases a single rum cake. I’ll supply the exact cake dimensions right after kickoff so you can size everything precisely.
• Material considerations: the model must respect common design constraints for bio-based composites—reasonable wall thicknesses, overhang angles that print cleanly, and tolerances suited to a typical FDM printer.
• Practical touches: friction-fit or hinge system that stays closed yet opens easily, enough airflow to keep condensation low, and a small flat area where I can later emboss or engrave a logo.
• Deliverables: STL ready for print, plus the editable source file (STEP or Fusion 360 preferred) and a brief note on print orientation, layer height, and infill you recommend for best results.

I’ll sign off once the files slice without errors in Cura/PrusaSlicer and a quick low-resolution test print confirms the parts mate correctly.
