The "3D Printing Calculator" helps users optimize 3D printing settings by calculating key parameters. Users select a printer (e.g., Creality CR-M4, Ender-3) and filament type (e.g., PLA, PETG, ABS, TPU), then adjust the nozzle size (0.2mm to 1.2mm) using a slider. Based on these inputs, it computes:

Layer Heights: Minimum (25% of nozzle size), standard (40%), and maximum (80%) layer heights for precise printing.

Flow Rate and Print Speed: Adjusted for the filament and nozzle size, ensuring proper extrusion (e.g., 3 mm³/s and 50 mm/s for PLA with a 0.4mm nozzle).

Printer Settings: Provides specific settings like nozzle and bed temperatures, retraction distance, retraction speed, fan speed, and flow rate ranges for the chosen printer and filament.

Printer Specs: Displays bed size and build volume for the selected printer.

It updates all values and settings dynamically as inputs change, aiding users in fine-tuning their 3D printing process for better results.
