These connectors are replacement joints for classic aluminium greenhouses, typically from the 1980s.
They are designed to join aluminium tubes used in the frame structure and come in both 3-way and 4-way versions.
Perfect for repairing or extending older greenhouse frames where the original plastic fittings have cracked or become brittle over time.
When printing, a brim is recommended for better bed adhesion, and supports should be set to “from build plate only.”
It’s also recommended to pre-drill the holes where the screws will be inserted.
The exact screw positions vary depending on the greenhouse model and tube profile, which is why no pre-drilled holes are included in the model.
