Laptop riser (with diving weight)

Needed a small riser form my MacBook Pro 2021 / M1 Pro. Could not find what I was looking for so I designed my own. Attached STL and Fusion 360 files (fully customised via parameters). Some features:

- the centre holds a diving weight for keeping everything nice and stable (dimensions are in the Fusion 360 parameters)
- gap in the centre to run cables neatly underneath the diving weight
- put 4 anti slip pads on the 4 posts, I used 8mm x 3 mm (but the Fusion 360 has config parameters for them)
