Press-release connector fittings for filament guide tubes. Sold in pairs.
New connectors purchased after May 2018 are of an updated, all-metal design. These connectors are more durable for longer life and cause less wear on the filament tubes. Updated part design is compatible with all generations of MAKEiT printer.
When one tube connector fails, it is recommended to replace the paired connector on the opposite end of the same tube.
