The Opportunity

Problem

Manufacturing course students can't find affordable, user-friendly CAD software that seamlessly integrates with 3D printing for prototypes due to high costs and steep learning curves.

Solution

ManuSketch provides 100+ ready templates for gears, brackets, enclosures common in courses, editable with simple parameters. Users tweak dimensions via sliders without drawing from scratch. Exports directly to STL with manufacturing tolerances baked in.

Target Audience

Students enrolled in manufacturing or engineering courses needing CAD for 3D printing prototypes

Differentiator

Course-specific parametric templates crowdsourced from professors.
