2D/3D CAD Prototype Tray

DXF / SVG (optional STEP/STP) Design for Handheld Snack & Beer Holder – Laser Cut Prototype
Project Description:
I am looking for an experienced CAD designer (2D/3D) to create files for a laser-cut prototype of a multifunctional handheld tray/grip.
What I need:

Ergonomic handheld tray shaped like a pistol grip / handle for one-hand use
Slot for 0.5 L cup (standard red plastic party cup, diameter ~8–9 cm)
Flat tray area for snacks (e.g. hot dog in bun + chips / nuts, with low rim)
Optional: phone holder / stand (for smartphone ~7–9 cm wide, preferably with angle adjustment)
Approximate overall dimensions: ~10 cm width × 50 cm length × 10 cm height (including handle) – open to your suggestions for better proportions and ergonomics

Required files:

Main: DXF and/or SVG (for laser cutting – cutting lines + engraving if needed)
Nice to have: 3D model in STEP / STP format (for assembly check and visualization)
