Mechanical Calculator

This fully mechanical calculator is designed to solve times tables in seconds. Entirely 3D-printed, it requires no glue, screws, or additional hardware for assembly, making it both innovative and accessible. Assembly: The calculator is designed for straightforward assembly, with all parts snapping or interlocking securely. No adhesives or special tools are needed, ensuring a seamless building experience. 📷 Image redacted — claim this model to add your own media For assembly I have provided a fully assembled model for reference to help you assemble your calculator 3D Printing: The base model presents a unique challenge, particularly for users who struggle with bed adhesion. To ensure success, using a raft is highly recommended. The base is compatible with printers featuring a build plate of at least 180 x 180 mm. Recommended Print Settings for All Parts: Supports: None Raft: Yes (recommended for the base) Print Speed: Max 120 mm/s First Layer: 20 mm/s Layer Height: 0.2 mm Infill: 15-20% (Grid or Gyroid recommended) Material: PLA Nozzle Temperature: 200-220°C (depending on filament) Bed Temperature: 50-60°C (if your printer supports it) Cooling Fan: Enabled (100% after the first few layers) Retraction Settings: Retraction Distance: 4-6 mm (for Bowden extruders) or 1-2 mm (for direct-drive extruders) Retraction Speed: 25-40 mm/s Color Change: At layer 3 (optional, for aesthetic details) This project offers an exciting opportunity for makers to test their 3D printing skills while creating a functional and engaging tool. With attention to detail and the right settings, your calculator will be both precise and durable.
