MATCH FIRST

Same diameter isn’t enough.

Check pitch, length, head clearance and drive size. Furniture screws may be self-tapping or proprietary. This tool makes a blunt, fully threaded machine screw with an approximate 60° profile.

PRINT ONE

Start with a fit test.

Import the STL in millimetres at 100% scale. Head-down orientation is supplied for convenience; layer direction affects strength. Try fine layers, keep supports off threads, and never force a tight fit.

KNOW THE LIMIT

Plastic isn’t a metal spare.

Small threads and repeated tightening are difficult. Resin or SLS can capture finer detail, but material and process still determine durability. Read the printing guidance ↗
