Description

This is a robust, 3D-printable cradle-style motor mount designed to securely hold the popular S30-300 DC Gear Motor, or any similar motor with a precise 32.25mm diameter body.

The design features a wide base with integrated mounting flanges and screw holes, ensuring excellent stability for your mechanical projects.

Key Features & Applications

  • Precision Fit: Designed specifically for the 32.25mm diameter of the S30-300 series.
  • High Stability: The wide base and dual screw holes prevent motor rotation and movement.
  • Versatile Use:
    • Dioramas & Nativity Scenes (Presepi): Perfect for securely mounting motors used to create slow, reliable movement for figures, water wheels, or other animated elements.
    • Robotics & DIY: Essential for low-RPM applications, small mechanisms, and hobby projects.
    • RC Models: Ideal for lightweight mechanical functions.

Print Settings Recommendations

 

For optimal strength and ease of printing, use these settings:

  • Material: PLA, PETG, or ABS. PETG is recommended for high durability.
  • Layer Height: 0.2mm.
  • Infill: 20% - 30% (Grid or Gyroid patterns work well).
  • Supports: Not necessary (the design is optimized for FDM printing).

 

Required Hardware

 

To mount the bracket to your project surface:

  • 2 x M3 Screws (Length depends on the thickness of your mounting surface).
