Problems with Snap Points

Trying to create a box storage mod where you can snap the boxes together but since im pretty new to modding im having trouble with the snap points. Anyone got a tutorial how to create snap points right?

Thanks in advance

Okay got a few snap points to work. Storage Box can not snap on top of each other and left/right.
Now i have a last snap point which doesnt want to work. I want to snap two boxes with the backside onto each other. Any idea?

Oh wow and now that i tested my mod on my server its really worse. Instead of placing the box on top of other like it worked in the dev kit, the box float now way behind in the air, even tho the snappoint shows right on top of the other box.

how did you make a snap point? if you don’t mind telling me.

I too would really like to hear how you managed this.
