this is also one of my first models (well my first handy model at least) i made this 1: because i was bored 2: i thought it was cool. and finally,  3: because i wanted to make something handy. and i had already 3d printed something very similar for my bed. I am personally very happy how it turned out. my tv was 1.4cm by the y axis and 0.9cm by the x axis. so you might need to tweak it for your own tv/monitor. also i needed to put a tiny bit of blue tack so it stays straight but feel free to tweak it.
