Бульдозер AF D4 1:14 RC

AF D4 – 1:14 Scale Remote-Controlled Bulldozer (3D Printable Model)

This detailed RC model is inspired by the iconic CAT D4 bulldozer and designed specifically for 3D printing enthusiasts and RC hobbyists. Featuring full remote-control functionality – from tracked drive to moving blade – it's both a challenging and rewarding build.

Optimized for FDM 3D printers with a 0.4 mm nozzle and minimum 20x20x20 cm bed size, most parts print support-free. The model is organized into clear assembly sections for easy navigation, and the files include a calibration STL to help ensure a perfect fit.

NOTE, the model has the ability to adjust the tension of the tracks - check manual!

⚠️ Before You Start

🛠️ Printer Calibration

Before starting the print, make sure your printer is properly calibrated.

In the ZIP package, you will find a file named test_part.stl – place a MR128ZZ bearing into it.

The bearing should fit with a slight resistance. If it does, your printer is well-calibrated.

🖨️ Print Settings

• This project is designed for FDM printers with a 0.4 mm nozzle and minimum 20x20x20 cm bed size
• Filament: PLA, PETG
  
• Layer height: 0.2 mm
  
• Infill: minimum 30% (any pattern is fine)
  
• Wall count: at least 3 walls (feel free to increase if needed)
  
• Most parts can be printed without supports
  
• Files that require supports are labeled, e.g., BL001_addsup.stl
  
• Alternatively, use pre-supported versions: BL001_presup.stl

🔁 Print Quantity

• The instruction includes information on how many pieces of each part to print
  
• Files that need to be printed multiple times include a multiplier in the file name, e.g., C004_x2.stl

📁 File Categories

The files are grouped into 5 sections based on their placement in the model:

• Base section
  
• Engine section
  
• Blade section
  
• Cabin section
  
• Tracks section

Each part in the ZIP archive has a unique identifier, which corresponds with those mentioned in the instructions.

🧷 Assembly Notes

• Some parts need to be glued together
  
• Use CA glue (cyanoacrylate) or any universal adhesive
  
• Parts requiring glue are clearly marked in the instructions

🎉 Final Note

I wish you tons of fun during the build – and even more once the model is complete!
