3D printer cooling fan
My largest print to date, a whopping 9 hour print. By various accounts the Ender 2 is missing a cooling fan so there are lots of mods available out there. I chose this one that incorporates a 5015 fan that I already had and moves the existing fan to one side to make the print head a bit more visible. The whole thing printed well but I was surprised how long it took to remove the support material from the middle of the piece. A bit of time to install it and I'm eager to do the next print now.
