Surface Pro hooks for fan support

The Surface is bad at dissipating heat when under load, but strap a couple of fans to it and it gives me literally double the frame rate.

So I created these hooks to hold the fans in place. I considered something more tailored to the fans, but really the elastic bands can do the job with any fan and all I need is the hooks to loop them around. 120mm fans look a bit silly, but are quieter than the 80mm ones so who cares how it looks?

I also considered inserting soft materials, but with the way these things work the screen is only under pressure at the very edge and with PLA and the rounded corners that I modelled, I think the risk is minimal.

I printed with 1mm wall/top/bottom thickness and 20% Cubic infill. It comes in at 1g , i.e. about 5 mins to print. I can't imagine needing more strength than that.
