IKEA Lack enclosure Air Filter intake

thingiverse

The next part of my cooling piece for my Lack enclosure has arrived. This filter is specifically designed to work seamlessly with my cooling duct (https://www.thingiverse.com/thing:3076576), although I'm also planning to create a modified transit duct so it can be used as a standalone unit. Sorry about the subpar finish in the photos, but I've just installed a brand-new build-tak surface on the printer bed and for some reason, someone thought it would be an excellent idea to print a massive logo and warnings in ink that gets all over your prints. To make matters worse, I experienced a bit of "Y" axis shift halfway 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's held securely in place by two air ducts that screw into the table and into the air duct attached to the printer. The filter support screen features a foam filter (Filter foam https://www.amazon.co.uk/gp/product/B01BO60PTO/ref=oh_aui_detailpage_o03_s00?ie=UTF8&psc=1) sandwiched between two layers, which is then slid into slots in the housing and secured by snapping the lid over the protruding part of the filter support grid. No additional fasteners are required. The housing itself is fairly substantial as I wanted to minimize airflow restrictions as much as possible. The filter area measures 120mm square, so it should impede the flow from an 80mm fan to a bare minimum. Air is drawn through the foam filter and into the enclosure via the fan on the control board cooling duct and cover, which not only cools the control board of the printer but also provides positive pressure to the enclosure to prevent dust and other particles from entering. There are two versions of the housing and lid available. The idea behind this is to provide users with an option between drawing fresh air from the side or underneath the housing. This allows them to decide whether to enclose the shelf beneath the printer or leave it open, depending on their specific needs and preferences regarding ventilation using the printer cooling fan.
