IKEA Lack Extractor Fan Assembly

thingiverse

This is my very first CAD design ever created. It's an extractor fan assembly designed specifically for use with IKEA Lack enclosure setups. The goal was to have one or two extractors mounted on top of the enclosure, extracting heat and fumes from the enclosure as needed when printing PLA or ABS. ----------------------------------------------------------------------------------------------------------------- ### Updates Update (2018/04/05): I printed out the bottom part of the fan assembly (IKEA_Lack_Extractor_Fan_Assembly_Bottom.stl) and noticed a small 1mm gap between the inner wall and one side of the fan mount. I corrected this error and uploaded the fixed STL file. Update (2018/04/05): After printing the top half of the assembly (IKEA_Lack_Extractor_Fan_Assembly_TOP.stl), I discovered another mistake in my design. When creating the slot system, I forgot that it would increase the height from 50mm to 48mm. Tomorrow, I will correct this and upload the new top half with an extra 2mm added. Update (2018/04/06): I made the necessary adjustments to the top half of the assembly, ensuring a precise fit. I plan to reprint the top assembly over the weekend and verify that all holes align properly. This should complete the functional build. Update (2018/04/06): Added duct mount functionality. Update (2018/04/09): The duct mount was slightly too large for its intended hole, so I made adjustments and uploaded the revised file. Additionally, I confirmed that all holes line up correctly, making this a complete and fully functional build. ----------------------------------------------------------------------------------------------------------------- ### Parts For this assembly, I purchased the following parts: - Scythe GlideStream 120mm PWM SC: https://www.amazon.co.uk/gp/product/B01D64OXA4/ The fan comes with a 3-speed controller switch that allows you to adjust RPMs according to your needs. I plan to rewire it to a control panel on the front of my enclosure (still working on this), which will enable me to turn fans on and off and adjust speed as required. There is a hole in the bottom part for running wiring through the enclosure. - Active Carbon Filter (2mm): https://www.amazon.co.uk/gp/product/B06XF5MWWK/ The active carbon filter should neutralize ABS fumes, but if it doesn't work, I'll design another top half with an adaptor for attaching a duct and pumping out ABS fumes through a window or something. - Flexible Fan Ducting: https://www.amazon.co.uk/White-Flexible-Fan-Ducting-Extractor/dp/B011OOQ9PA/ I added a duct mount so you can attach 100mm (4" in freedom units) flexible fan ducting. I also included a notch around the mount to secure ducting with a zip tie (less than 5mm thick). You'll need 4 x M3 screws and nuts to hold the fan and whole assembly together, including the duct mount if using. Based on my estimates, you'll require 40mm M3 screws without the duct or 42mm screws with it. ----------------------------------------------------------------------------------------------------------------- Here are the TinkerCAD files for remixing: https://www.tinkercad.com/things/25ztyGigLsC# As this is my first attempt at creating a CAD design for 3D printing, I welcome any feedback. Suggestions on optimizing the design for 3D printing are also appreciated.
