#crbox designed for travel. Packs into a suitcase with room for clothes and gives (estimated) 200-350 cfm cadr (raw is 632 cfm) Assembles and packs in < 5 mins. No tape. At 350 cfm it’s loud. But can easily turn down. Can be powered by 12v usbc. Assembly video next 
Assembly video for small CR box for travel. Total assembly time < 5 mins.
Lots of inspiration from @Mw_ottawa @ee_kelsey @CRBoxKits @robwiss @cleanairkits and multiple others.
If anyone else actually wants them, I'm happy to share Fusion360 file, 3d printed parts, and dxf files for part cutting.
Used pieces from @sendcutsend because I wanted to keep the size down for travel. (e.g. 1mm thin aluminum panel for top fans, chipboard cutouts for sides, and MDF base plate)
Fans are Noctua NF-A14 iPPC-3000 (yes, they are loud on max, but it's still 150-200 CFM CADR even at a more normal volume)
Would love to see/hear/brainstorm other small designs that might be more packable.
Control box is a combo of ebay.com/itm/3252736931… and amazon.com/gp/product/B08… with a little 3d printed case.
Okay, enough people wanted the instructions, here they are along with all the models.
