Laptop (Lenovo Yoga L13) cooling wedges

I have a laptop (Lenovo L13 Yoga) that, when stressed a bit, can become very hot and noisy. The thing isn't helped by the fact that all the venting zones are on the underside, and if you lay it on some kind of softish surface (just a table cloth suffices) the effectiveness of cooling is even worse.

I *know* that there are bases you can buy to keep it separated from the table (and some of them even have their own extra cooling), but they're big,there are bases you can buy to keep it separated from the table (and some even have their own extra cooling), but they're big, and in the end and in the end, you never bring them along.

So I designed and printed a couple of small wedges that fits nicely, are more than sufficient to keep the laptop vents separated from the table, and fit everywhere in your bag.

They are very specific to my model, but you have the source code here so you can adapt them to your own laptop quite easily. The source is highly commented.
