IKEA Lack enclosure Air Filter intake by Gnattycole

Last crawled date: 3 years, 1 month ago

The next part of the cooling piece for my Lack enclosure. This filter is designed to be used with my cooling duct (https://www.thingiverse.com/thing:3076576) although I may make a modified transit duct so it can be used as a stand alone unit. Apologies for the poor finish in the photos but I've just fitted a new build-tak surface to the printer bed and for some reason, someone thought it would be a great idea to print a great big logo on it and some warnings in an ink that comes off all over your prints. I also had a bit of "Y" axis shift about half way through the print due to a bed collision with my cat.
The filter is designed to be underslung mounted beneath the printer deck (i.e. The Ikea Lack cardboard table top). It is held in place by the two air ducts which screw through the table and into the air duct which is attached to the printer. It has a filter support screen in which a foam filter is sandwiched (Filter foamhttps://www.amazon.co.uk/gp/product/B01BO60PTO/ref=oh_aui_detailpage_o03_s00?ie=UTF8&psc=1 ). The filter is slid into the slots in the housing and the lid is slid over the protruding bit of the filter support grid and snapped into place on the housing. No additional fasteners are required. The housing is fairly substantial as I wanted to restrict the airflow as little as possible. The filter area is 120mm square so should impede the 80mm fan flow to a minimum.
Air is drawn through the foam filter and into the enclosure via the fan on the control board cooling duct and cover, which both cools the control board of the printer and provides a positive pressure to the enclosure to prevent the ingress of dust etc.
There are two versions of the housing and lid. The idea is to provide option on whether the fresh air is drawn from the side or underneath the housing. This is to enable the shelf beneath the printer to be enclosed or left open and whether the area is required to be ventilated using the printer cooling fan.
