This is a remix of the trays from Yuan4114's https://www.thingiverse.com/thing:647425, which is a remix of Gushie's http://www.thingiverse.com/thing:447213, which is a remix of 1986breeze's http://www.thingiverse.com/thing:234669, which is a remix of martinhering's http://www.thingiverse.com/thing:177814

The Trays in the previous version were made to only be one in each box. I thought it'd make better use of the space if you could also stack the trays themselves. I shortened the center wall, and for the bottom tray (v2) I added side supports to keep the top tray straight.

You can use the v2 trays on the top and the bottom just fine, but I included the v1 version as well which you can use for the top tray since you dont actually need the side support arms on that one, since there's no more trays it needs to support. (if someone remixes a 2x tall box someday maybe it'll be needed :P )

My Prints were at 150% scale which I recommend (or bigger), but they also print and work just fine at 100% scale.

NOTE: I did not include Yuan4114's boxes themselves in this zip, so click the first link in the description to get those, and just use my trays instead.

They still work just fine as a single tray too, so you can do that if you want, with the flexibility of adding more later.
