Screw Specification Visual Pattern Collection

This is a set of screw specification visual patterns optimized for 3D printing, tool wall panels, and parts box classification labels. It includes mainstream screw head types, tail types, and over 20 recess types on the market.

Optimization points
- 4x Scale: All patterns are designed and laid out in multiples of 4, perfectly compatible with 0.2-0.8mm nozzles for printing.
- Chamfers: Micro chamfer optimization has been uniformly added to the pattern edges, effectively reducing edge overflow and right-angle overshoot, further enhancing print sharpness at low layer heights.

Printing recommendations
- Minimum size: With a 0.4mm nozzle, most patterns can be supported down to 6.4mm × 6.4mm;
- Recommended size: To ensure perfect presentation of recess details (such as Torx, Phillips, and other complex micro-structures), it is recommended to use at least 7.2mm × 7.2mm for daily use.
