Adjustable Laptop Stand [WIP]

This is a little project I'm working on. It's an adjustable laptop stand. My idea is to make it as flat as possible when closed and adjustable in height so you can put the laptop at the angle you prefer. This is still a work in progress, I'm thinking about how to improve it, but it is usable right now! It's made of 5 pieces: the bottom piece: this piece goes attached to the laptop. It holds the adjustable pieces and it has some grooves to adjust the height. It also have 4 small holes where it touches the laptop so you can print the feet like in TPU to increase the grip in the PC (black piece in the photo); the feet: it's just a cylinder that goes on the bottom piece. You have (if you want it) to print 4 of it. In the photos this part is missing 'cause I don't have the TPU to print it; the adjustable pieces: this are 2 pieces that goes together. They snap into each other so you can move them without problems. One of them snaps into the bottom piece, the other
