Large laptop stand (15") dovetail remix

Remix of https://www.thingiverse.com/thing:2886695

While the original large laptop stand was perfect for my large Dell 5501, I didn't like how the parts had to be glued together with little guidance. So I made the parts snap together using a dovetail joint instead. It might still need glue to stay together depending on your print, but I have been fine without.
I also reduced the length of the center bar to 195mm (joints excluded) in order to fit the two sides between the rubber feet on my laptop.

I tried printing with the center bar having 0 tolerance, but it caused the side part to bend slightly out of shape. So I cheated a bit and just reduced the width of the center bar to 99% in Prusa Slicer and exported the result. This worked fine for me but your mileage may wary.
The original center bar at width 31.00mm is v1, my 99% width hack at 30.69mm is labeled as 99w.
