Flsun T1 expanding pliers for parallel arms

Flsun T1 arm widening pliers

• Extends the spring to extract the ball joint rods.
• Two versions, short and long. The short will be more maneuverable, and the longer more stable and require less force.

Printing

• Print oriented as shown in the pictures.
• Use supports as indicated.

Mouting

• Lock the pin with a piece of filament when mounted.

Usage

(As I don't own a T1 yet, thanks to @PTJim_2477983 for description and printer pictures)

It's easier and safer to loosen the effector screws and spread apart just one side at a time (then removing the other side manually, without the pliers), to keep parts from flying away - take care to not lose the little cylindrical bushing while doing so. Note that the tiny little outboard Allen hex screw should be tightened down first, as it seems to be there to hold the attachment rod in place for the larger screw, which could shift the attachment rod slightly out of place while tightening. 

For easier re-installation, remember to pre-position the ball-joint attachment rod to align perpendicular with the effector frame as much as possible. It's a little stiff, but it moves and rotates and will slip right in if aligned properly. Near the end of pliers compression, if you squeeze slowly and gently, you'll have a lot of control to get the attachment rods lined up just right for reinsertion, as slight movements of the pliers will allow positioning of the rod at the entrance to the effector receiving hole before releasing the pliers.
