3D-Printable Aluminum Finger CAD

I need a complete set of CAD files for five articulated, life-sized human fingers that will be printed in hollow aluminium with a constant 1 mm wall thickness. Because the design must go straight to prototyping, every segment has to include believable joint geometry (pin, hinge or similar) but I am not chasing photorealistic skin textures—function first, form second.

There are no previous sketches or meshes to start from, so the entire kinematic layout, tube routing and clearances will be created from scratch. I expect the model to remain lightweight enough for metal additive-manufacturing constraints while still allowing a full range of finger motion.

Deliverables:
• Full parametric source files (STEP or native SolidWorks / Fusion 360)
• Print-ready STL for each individual phalanx and any mating pins
• A brief build note highlighting joint tolerances, minimum feature sizes and orientation recommendations for aluminium powder-bed fusion

I will sign off once each finger’s joints move freely in the CAD assembly, the 1 mm wall requirement is consistent throughout, and all parts export without manifold errors.
