How to make a part appear at your hand

trying to make star finger in jojo but i need to find a way to put the finger at the stand

like this :

you need to be more specific on what you need to make.

You can use WeldConstraints to join the parts or Motor6Ds if they are going to be animated

Create the weld/motor6d when they summoned the stand with the function, or use the Clone() function if you already have the welds.

Then make the C0 and C1 of the joints to their respective parts.
