This template generates tube adapters, with one inlet and one outlet (each of which can be considered either male or female).
Both tube ends are customizable. It is possible to offset the two connectors. Likewise, each end can feature a thread on the outside, inside, both, or none.
Internal fillets are always integrated into the adapter to optimize the flow through the transition zone.
Note that a clearance is always required: a tube with an outer diameter of 50 mm will not fit into a tube with an inner diameter of 50 mm (even more so with 3D printing).
Strictly speaking, this template can also be used to create custom funnels, such as model #1342.

Additional information
The transition refers to the connection interface between the two tubes. It defines the total length of the adapter, which is equal to the sum of the tube lengths plus the length of the transition.
