This is a addon Stand for the Microsoft Surface Pro (first version) to make it lower since the integrated flip out only has 1 upright position. Easily clips on.
The legs themselves are not included, just cut a 6mm wood or carbon fibre bar or tube to the length you want (6cm is fine I find)
The clip is not super strong but OK.
It closes a few of the ventilation holes but I don't think this will have a huge effet.
There is a 3mm hole through the entire length to put in a carbon fibre bar for extra strength and locking. A 2,5mm dia bar will easily fit.
I don't guarantee anything. Use at your own risk. Works fine for me.
