Heavy Duty Flat Mending Plates | 20x4mm (M4)

This is a versatile set of structural flat plates designed for joining, reinforcing, or extending your DIY projects.

Unlike thin spacers, these are designed to be structural. With a 4mm thickness and 20mm width, they are rigid enough to replace metal mending plates in 3D printed assemblies, light furniture repairs, or robotics prototyping.

Specifications:

• Width: 20mm
• Thickness: 4mm (Sturdy & Rigid)
• Hole Diameter: 4.5mm (Optimized clearance for M4 screws/bolts)

The Set Includes (Lengths):

• 40mm
• 50mm
• 60mm
• 80mm
• 90mm
• 100mm

Applications:

• Connecting two 3D printed parts together.
• Reinforcing corners or seams.
• Creating custom linkages or levers.
• Spacers for mechanical assemblies.

Printing Instructions:

• Material: PETG or ASA recommended for mechanical stress. PLA is fine for static rigid connections.
• Infill: 100% (Solid) is recommended for maximum strength around the bolt holes.
• Walls: If not printing solid, use at least 4-5 perimeters.
