Printer Enclosure Air Cleaner

thingiverse

I wanted a filter for ABS fumes and didn't find anything to my liking, so I created this solution. It prints without supports and is modular, allowing you to add or remove "cells" according to the size of your printer enclosure in 2-inch increments. The fan supports are sized for a specific fan, but the blower end is designed to accommodate different fan mounts if a different fan is used. I haven't extensively tested it, but it does move air from the enclosure through the carbon filters, meeting my functional requirements. Whether its use is validated will be based on experience as I print ABS parts (usually I print PLA, so experience will accumulate slowly). Print Settings: Printer: QIDI Tech I Rafts: Doesn't Matter Supports: No Resolution: 0.2mm Infill: 20-30% Notes: The parts are designed to be printed together as shown in the picture. This may require some manipulation in your slicer. Print as many filter housings as needed for your enclosure size, with each housing roughly 2 inches long. Post-Printing: Additional Parts: A blower, filter pads, and a gasket are required. For the blower, I used this one: https://smile.amazon.com/gp/product/B016UCKBUA/ref=oh_aui_search_detailpage?ie=UTF8&psc=1 The blower fit imperfectly, but trimming and coercion allowed it to work. Filter pads can be any large enough material; I used these: https://smile.amazon.com/gp/product/B00L2NZOKK/ref=oh_aui_search_detailpage?ie=UTF8&psc=1. A "gripper pad" or similar material is required for the gasket, around 1.5mm thick. Assembly: 1) Cut your filter pads to size: each cell needs 2" x 5.25" of filter pad. 2) Stuff the filter pads into the filter cells; it should be obvious how they fit. 3) Attach the first filter cell to the blower block, then attach remaining cells and finish with an end plate. 4) Slide top and bottom blower plates into the supplied slots in the blower block. 5) Add gasket material around the hole; method determined by chosen material. 6) Install the blower in an obvious way. 7) Find a power supply for your fan (I repurposed an old wireless router power supply). This design was created in Solidworks.
