IKEA Lack Enclosure Anet A6 cooling duct assembly

cults3d

Following up from my control board cooling fan cover, I needed a method to draw in cool air from outside the enclosure as I suspected there could be a high likelihood of the enclosure temperature rising significantly when printing with ABS. I also wanted to create a slight positive pressure inside the enclosure to prevent dust entry. The intake cover is designed to use the fan screws to attach it to the existing cooling fan, which is attached to the control board cover using the standard mortise and tenon joint from the original Anet control board cover. The cover has two threaded holes in the base that accept the intake transit pieces. A drilling jig is provided for accurate drilling of the Lack table top; the holes should be opened up to 42-44mm using a proprietary hole-saw or Forstner bit. The fan inspection cover has been designed to accept a 60mm perspex disc to enable the fan rotation to be viewed. I've uploaded a solid one for those who do not wish to glue the window into the cover, and it is also streamlined to aid airflow to the fan. Either cover is a friction fit using stubs that locate in the fan mounting turret screw holes. The window cover can be removed using one of those suction cups used to change halogen GU10 bulbs. The plain cover has been designed to have a knob mounted with an M3 x 14mm screw and nut, which is held captive in the knob. The next stage is to design a filter box to be mounted on the underside of the printer deck (also known as Ikea cardboard furniture) and possibly incorporate an additional booster fan if necessary. Update: September 8th, 2018. Filter housing now built and tested; see https://www.thingiverse.com/thing:3090158. I've added the STL's on here but the details are on the link.
