All parts can be printed without support.
Print with flat side down.
It is recommended to print (at least the middle part) in a heat-resistant material.
Overhang is limited as much as possible (no more than 65°).
Measure the socket as there seems to be some difference between the standards ...
There is a version for 36 mm sockets and one for 40 mm sockets. (only the first set is different)
