hi, just a little question, where do you plug the additional fan ?

Also, do you think it could be a good idea to put one under to inject fresh air directly into the PSU/Motherboard and one at the top to extract the hot air/abs vapors on the top ? In this case, where would you plug the two fans ?

Thanks for this wonderful design :)

Nice design man. I have a question if i want to make this for a 80mm fan i can resize your design to 90mm? for example your IKEA_Lack_Extractor_Fan_Assembly_Bottom file in cura is X 130mm Y 130mm so i think if i make them X Y 90mm i can fit a 80mm fan?

Same for the _TOP and the_DUCK in cura is 120mm and i just resize it to 80mm

What do you think? should work right? :)


Heyho. This looks brilliant and I wanted to design something like that myself, but I guess now I don't need to.

Since I guess you built this already and know about the insides of an Ikea LACK table, how did you get a smooth hole in your table?

Thanks again.


Sorry for the late reply, I hadn't spotted this.

I've attached the TinkerCAD plans I did for my enclosure to show you how I did it:

  1. The first step (LACK 1.PNG) is to cut out one of the sides of the table and scoop out the cardboard support. I did this by drilling a hole into the side and then used a jigsaw to cut out the rest. At this point, be careful as without the cardboard support the table top flexes under pressure and can break..

  2. The second step is to cut out the square holes for the fan assembly (LACK 2.PNG). You will have to measure the square and it's position no the top and bottom part of the table very carefully to make sure the holes line up (you have to cut them separately)

  3. Third step is to install the fan assembly (LACK 3.PNG)

At this point, it's up to you how you wire it up and to what. For my assembly, I actually installed a powersupply, cooling fan, and power socket inside the cavity so that it's all self contained (makes it easier to remove the enclosure when you need it). I've crudely outlined how I laid it out in LACK 4.PNG. Depending on the power supply, you may need to cut a hole at the bottom f the table so that it fits.

I've still not finished the project. I still plan to wire some LED lighting to the powersupply and install a front panel to control the fan speed and lighting.

Thank you very very much for elaborating ... I have printed it but currently I just leave the enclosure door open a bit for ventilation - Next maintenance on the printer will be the day though. I have a spare relay channel that I can use for the fan, controlled externally, so the electronics side is taken care of.
