I got a couple of little oscillating clip-on USB desk fans. They are about 6 inches. Got them off Amazon for about $20 each. The clip-on doesn’t work well with tent poles but zip ties fix that. Oh and they didn’t come with a plug. Just the USB cord. I did go buy a 10 ft. USB cord and a dual USB plug. I have 2 in a 2×4 as well as a small Vizosun clip-on fan but that doesn’t oscillate but clips onto poles just peachy.
