I have been looking for a mount for a fan for my wade extruder on my prusa i3 so I decided to make this one. Will be printing it out tomorrow for a test run. Attaching a messy SW file EDIT: I am thinking of making a partial airstream to go straight on the J-head so for it as not to jam. Keep looking here for updates. Now updated to V2 with smoother edges, a ventilation hole for the extruder and improved flow. Also bigger size for the screws (now 4mm)Print in ABS as for the hight temperatures near the nozzle. I printed it at 0.2mm layers. Needs no support
