Just get another 24v fan =) (and cable, and solder ir, etc etc). V2 - Washers to raise it a bit if you use shorter nozzles. Unfinished V3 It has a small problem of height and I didn't finished, but printed with it and did show great results. I'll most probably won't finish it since now I use a totally different setup.Fell free to change it, I think it has a problem of 0.5mm, not much more than 1 mm. Added V3 Unfinished. The area that it's close to the nozzle needs a heat insulator film so it don't bends (on pla)
