Would be nice to speed dry the sleeves, but only if it actually works…
If you have a 3d printer this should be much cheaper than around $60 USD,
I’ve just given mine it’s first run. The case fits nicely into the Air’s connector ring, the adaptors for other size cases (Flight, Go and Quickshot) fit well also. I ran it for the recommended time (setting 1 for Quickshot, 2 for Go/Flight and 3 for normal full sized sleeves) and the sleeve I’d put onto the Air was fully dried and ready to be stored away for another day. The device isn’t the quietest thing in the world as it’s a running fan, however it’s not obnoxiously loud.
Hope this helps.
