Six short guides and one cheat sheet. Parts designed with these print cheaper, arrive sooner, and don't come back.
thin walls warp and snap — 1.6 mm if it takes load
drill anything smaller after printing
per side, for parts that slide together
6 mm tall minimum to stay legible
past that we add supports — free, but leaves witness marks
printed threads strip; heat-set brass doesn't
How thick is thick enough — and when a rib beats a solid chunk.
Read →Why vertical holes print small, the clearances that actually fit first try, and when the right answer is a drill bit.
Read →What ±0.
Read →Heat-set inserts, captive nuts, screws into plastic — and the one case where printed threads are actually fine.
Read →Layers are the grain of the part.
Read →A decision tree from "indoors, no load" to "replaces machined metal" — every material we stock, and the honest reasons to pick each.
Read →STEP is best — exact geometry, no faceting. Export in millimetres.
Quantity is set in the quote tool, not by duplicating bodies.
Holes, flipped normals, near-degenerate faces — fixed automatically, and the quote tells you what changed.
