3D Print Toolkit Design better-fitting 3D printed parts with powerful calculators built specifically for makers, hobbyists, engineers, and machine shops. 3D Print Toolkit helps eliminate guesswork when creating functional printed parts by providing tools for hole sizing, thread compensation, and thread reference calculations—all in one easy-to-use app. Whether you're printing bolt holes, threaded adapters, enclosures, or precision mechanical parts, these tools can help reduce trial-and-error and improve first-print success. Features Hole Compensation Calculator • Calculate the diameter adjustment needed for holes that print undersized. • Improve bolt, pin, shaft, and bearing fits. • Supports both inch and metric measurements. • Displays recommended compensation instantly. Thread Compensation Calculator • Adjust internal and external thread sizes for your specific 3D printer. • Fine-tune thread clearance based on real printed measurements. • Save calibration values for different printers, materials, and nozzle sizes. • Reduce repeated test prints and improve thread fit. Thread Reference Calculator • Quickly look up common thread dimensions. • Supports both Metric and Unified (UNC/UNF) thread standards. • Displays major diameter, pitch, tap drill size, and other useful machining references. • Great for designing printable threaded parts or preparing CAD models. Printer Profiles • Save calibration settings for multiple printers. • Store different offsets for PLA, PETG, ABS, TPU, and other materials. • Keep notes on successful print settings. Designed for Real-World Printing Perfect for: Functional parts Threaded adapters Replacement parts CNC and CAD projects Mechanical assemblies Workshop fabrication Engineering prototypes Privacy • No account required. • No subscriptions. • No internet connection required. • No ads. • All calculations and saved data remain on your device. Spend less time printing test parts and more time creating parts that fit the first time.
