Prints without support, as long as it's lying on its back. Mine's PLA and I haven't had problems with it melting, but I always have the blower running. Mounts to the X sled with the standard bolts. Re-uses the hotend fan, or you can fit a thicker, quieter one. You'll need M3 screws to mount both the fan and the blower, and the length will depend on the fans you choose.
