This Mini Forcible Entry Door is a 3D-printed scale model (approx. 1:10) of a classic breaching door used in firefighter and rescue training, only much smaller and desk-friendly.

It works both as a display piece and as a dry-training prop:

• You can set a mini Halligan tool into the gap, flex the door, and practice placing the wedge.
• Please note: the stiffness of the door is not comparable to a metal forcible entry door so training may not be 100% accurate.

Assembly

The model is printed in multiple parts and can be assembled easily.
Additional parts required:

• 2 × M3x20 screws
• 2 × M3 self-locking nuts
• A few drops of super glue
• Reinforcement pin: wooden skewer (higher stability but impossible to break) or balsa wood stick (recommended for extra realistic training).

Step-by-step Assembly

1. Attach the protector to the door:
   • Apply 2–3 drops of super glue into the recessed groove on the door.
   • Slide the protector piece into the groove until it fits snugly.
2. Mount the door to the frame:
   • Screw the door leaf to the frame using the M3 screws and nuts.
3. Prepare the base:
   • Glue the floor plates into the ground plate.
4. Assemble the frame onto the base:
   • Insert the door frame onto the pegs of the ground plate.
   • No glue needed – the fit is tight enough to hold securely.
5. Finished!
   • Your Mini Forcible Entry Door is ready for display or dry-training.

Print Recommendations

For best durability and functionality, the following settings are recommended:

• Main structural parts (door leaf, frame, ground plate):
  • 6–7 perimeters (wall lines)
  • 30% infill (e.g. gyroid)
  • 5 top layers / 5 bottom layers
  • Brim around the part for better adhesion
  • Support only required for the door leaf (standard support is recommended, do not use tree-support)
• Accessories (Halligan tool, wedge):
  • 100% infill (concentric) for maximum stability
  • Layer height: 0.12 mm for high detail
• Floor plates:
  • Standard print settings are fine
  • Layer height: 0.2 mm
• Supports:

  • Only required for the door leaf (use standard support settings)
