Connectors for wood (shelf)

Series of 3D Printed Connectors and Brackets

These models were designed for universal use in mounting shelves, structures, frames, and various fastenings. The models are optimized for 3D printing and have been tested when printing with PLA, PETG HF, and ABS materials.

• PLA – suitable for general indoor use.
• PETG HF – higher strength and better durability.
• ABS – suitable for outdoor use and higher loads.

For heavier loads, it is recommended to use models with reinforcements and greater material thickness.

Recommendation by load

• For light use, PLA is sufficient.
• For higher strength and longer lifespan, PETG HF is recommended.
• For outdoor use and higher mechanical loads, ABS is most suitable.
• For high loads, it is recommended to choose models with reinforcements and greater material thickness.

These models are suitable for home workshops, shelves, workbenches, technical structures, and various assembly projects.
