A Mechanical Freelancing Hub

We're working on a mechanical plastic mouse trap and need a complete 3D model that captures every functional part and shows how those parts move together. The emphasis is on accurate, production-ready geometry rather than photorealistic textures.

Clearances between parts should reflect realistic plastic tolerances so the trap can be prototyped without extra rework.
 

Key Scope & Technical Requirements:
• Convert STL/OBJ mesh → parametric CAD model
• Rebuild 5 helical flow channels using true circular cross-sections
• Use sweep/centerline-based modeling (no faceted geometry)

Geometry & Design Control:
• Enable parametric control of channel diameter
• Ensure proportional body scaling (non-uniform, relation-driven)

We need a skilled 3D designer to create a factory-style housing for an aftermarket CarPlay/Android Auto screen that will sit seamlessly in the dashboard of a GreatWall C20.
The finished part should look like it rolled out of the assembly line—no visible cables, gaps, or “stuck-on” appearance. 

 Key details:
• Measurements: we'll supply exact screen & cut-out dimensions 

We've a wooden stool with huge dowels and we want to attach an assembly that can allow a pencil pot to be slotted onto the wooden dowel the whole point is the pencil pot is able to be detached and removed when needed. There are two parts that need to be designed.
1. The immovable base which will be permanently attached to the stool
2. The pencil pot with a slot 

We've an early concept for a multi-purpose woodturning tool and we need to turn that idea into a build-ready prototype. Your primary task is to translate the concept into detailed 3D CAD and engineering drawings.

The finished design must handle both hardwoods and softwoods without swapping cutters mid-project, so balance, vibration control and edge durability are critical.
