A simple Macbook stand - there are 2 versions standard and long.

Standard - It should fit 13 inch MacBook models, a bit to short for Macbook Pro 15 the screen changes balance
Long - I am using it with my Macbook Pro 15.4" 2016 version and it works fine

Prints without support, I have added 5 line wide brim to make sure that it stays on the platform while printing.

Parts for assembly:
4 x M4 bolts 16mm long
4 x M4 nuts
