AF D4 bulldozer 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, 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.

📦 The download package includes:

• All STL files organized by function
  
• A detailed assembly guide
  
• A complete hardware list (screws, electronics, and mechanics)

🚀 Print it, build it, bring it to life! 🛠️🚜

⚠️ 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.
  
• 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 – you can generate supports in your slicer.
  
• Alternatively, you can use pre-supported versions of the files – labeled as 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 – print 2 pieces of this part.

📁 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!
