I haven't talked about this on here, but I've been working on a design for a low-cost air purifier (<$100) suitable for a kid's bedroom. Looks like this (iphone X for scale)
@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 neato! What's the widest point of the print? Fairly sizeable printer needed?
@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!
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!
@Kels_316 how much juice do those fans use? Would you be able to run it overnight on a smaller mobile recharge brick?
@Kels_316 wait you already answered this
@mil yeah the idea was that it could run overnight if the power goes out. The original version did 12hrs but the fan was a bit weak on static pressure. I'm testing it with a really cheap bunnings 10,000maH powerbank but it only takes about 6000maH in reality.
@Kels_316 now just dont let the child leave the room
