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

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

Before you start

• 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.

• This project is designed for FDM printers with a 0.4 mm nozzle and minimum 20x20x20 cm bed size.
• 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.

• 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.

• 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.

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

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