here's a clip of it clearing smoke from a plastic box. This was a 2min test to see if the fan had enough static pressure to draw through the filter. I sped up the clip so it takes 10sec.
@Kels_316 This is awesome.
@Kels_316 the future is both amazing (3D print a machine) and horrible (air purifier for child’s bedroom)
@liamvhogan yeah it's dystopian scifi areas.
@Kels_316 @liamvhogan There's probably a word in German for dystopiawesome.
@Kels_316 neato! What's the widest point of the print? Fairly sizeable printer needed?
@twiddlekins 190mm
@Kels_316 bugger, just a bit big for mine!
@twiddlekins you could do it in four parts and glue it together, let me play with the file and see if I can make it work. What sort of printer do you have?
@Kels_316 I figured it could probably be split. Flashforge Dreamer
@twiddlekins split into 4, put a .25mm gap on the slots so it should go together without much sanding. Had to lose the '12v' under the socket. Biggest dimension is 136mm now, should fit?
@twiddlekins you'll have to use supports under the notches
@Kels_316 should do yup!
@twiddlekins I should have the info to upload a bit later today, I'll put the STL files for this version up as well. Will post a link. If you print it let me know how you go.
@Kels_316 I shall do!
@twiddlekins github page is here: https://github.com/Kels316/DIY-Air-Purifier/blob/master/README.md
it has a folder for the quartered STLs. Have fun!
@Kels_316 cool thanks I'll have a look!
@Kels_316 two halves printed up and joined. Pretty good fit with just the slightest bit of post processing! Will finish the other two tomorrow.
@twiddlekins ah nice one!
@Kels_316
Thank you, this is the kind of problem solving we need. Overconsumption and greed has gotten us into this mess, the least we can do is mitigate with community, pragmatism, and open source.
@boyd strong agreement!
so over the next couple of days I'll tidy up the design files and upload them to github with the BOM and some instructions. You do need to be able to solder to make the connector plug, and have access to a 3D printer for the top piece.
