Technic ball socket pieces

Collection of ball socket pieces, often used in Lego Bionicle sets and MOCs. This includes official ones, and custom designs, expanding the line.
Original shape taken from Stud.io, then modified in 3ds max

Recommended print settings:
Scale: 40%
Layer height: 0.1 mm
Horizontal expansion: -0.1 mm
Fan speed: 100%
Supports: No

I recommend placing 3d model on 3d printing bed in such way, that round ends of ball socket got maximum cooling from the fans.
