‎So here’s the story.

‎I recently felt nauseous, and it turns out it was probably from inhaling too much styrene while experimenting with ABS filament for the first time. Long story short, I discovered the Bento Box design by thrutheframe. I printed it using PLA+—the filament I’m most comfortable with—then picked up everything else I needed: activated carbon, a HEPA filter, magnets, screws, fans, cables, and more. I’m no engineer by any stretch, but after putting it all together, it actually seemed to work. The air around the printer felt noticeably different when I switched it on. I’m genuinely grateful and inspired. I’ll probably need a proper smoke detector at some point to confirm everything… but that’s not quite in the budget yet. 😅

‎I honestly felt it worked so well that I considered building one for other rooms too—especially since I have a toddler. That got me thinking about creating a similar design that could be adapted for other combination of filter medias or functionality, and therefore be more affordable from my point of view.

‎So here it is: my prototype for Chimney, my adaptable air-filtration blocks. If you’d like to share your thoughts, I’d really appreciate it. Just remember—I’m not an engineer, just curious—so feel free to share those thoughts whether you think it actually works. 😁😅

You can check the attached pdf for more info, and visit https://drive.google.com/drive/folders/1mhE_BF_msLXBLvnoJp_1C2tSIRJYcx-W for the assembly and other vids.

Sorry the models weren’t printed in the highest quality, but they should be good enough as prototypes. Feel free to adjust the print settings in the 3MF files according to your preferences.

‎If you enjoy what I’m doing and want to support my fiddlings (or buy me a coffee), you can reach me through ko-fi.com/franshds or paypal.me/franshds. I’d truly appreciate it.

Thanks! ☕
