Three tracks, from driving the editor to printing parts that fit and building mechanisms that move. Pick a path and work through it section by section.
Driving the editor

Building mechanisms
Coming soonSnap-fits, gears and joints: the moving parts, from first principles to parts that actually move.

Designing for FDM
How molten plastic actually stacks up — orientation, overhangs and the wall-and-infill choices that decide whether a part prints clean.
Tolerances and fits
Clearance, transition and interference fits, and the real-world gaps that make printed parts slot together.
Strength and structure
Where FDM parts break and how to stop them — layer adhesion, ribs, living hinges and shedding weight without losing stiffness.
Threads, fasteners and hardware
Threads, heat-set inserts, captive nuts and snap-fits: joining printed parts to hardware that actually holds.
From model to print
From a finished body to a clean print — exporting, the built-in slicer, print settings and a first layer that sticks.
Validate before you print
Prove it before you commit filament — simulate, print test coupons and measure your way to a part that fits.
