I had issues using the original design with my Macbook Pro 15 inch (Mid 2014). My Macbook was falling backwards. The design also didn't look very stable.
So I fixed that problem by increasing the length of the design and adding a support in the middle of the stand.
In the images you can see and compare the old design on the left and the new on the right.
If you want to support my work, you can leave me a tip, so I can buy a few cups of coffee:
