This is a 3 part print. Base, Top and the lock.
What is needed
How to assemble
You could have it on the left of right side of your laptop. Choose stls and 3mfs accordingly.
I can make magnet free version of it but then you will have to attach a 3D printed part at the back of your phone. I will do it only if i get enough requests for it.
Happy Printing!
