This is a clip that allows you to attach a 7" Elecrow touchscreen in this printed case to a MacBook Pro. I've included the original F3D file so you can change the parameters (monitorCaseThickness for the external display and screenThickness for your laptop's display) to suit your needs. It fits perfectly for me and doesn't require any additional rubber pads, but you could expand it a bit and add some.

I printed them on my Ender 3v2 in PLA at 0.3 thickness with a raft because the little star flanges around the large rounded corner don't print well without one. In reality, those flanges don't actually print well at all on mine, but they do give it a little bit of flex.

It'll work on the side or the top, I discovered, but I prefer the side. You should probably print two for sturdiness -- one works, but personally I just feel like it's more robust with two.

This is my first thing I've uploaded a design for ever! It's a weird little niche object, but I hope you find it useful
