Stacking paper is by far the superior way to store paper compared to hanging file folders, which allows paper to bend and warp. Anyone who'd like to keep their paper flat in a stack and organized, here's a design for you!

These divider trays hold letter-sized (8.5" x 11") paper. The metric dimensions are around 30 cm long, 23.5 cm wide, 2cm high.

If your paper stack is higher than 2cm, that won't work out: split that >2cm high paper stack to into 2 trays.

The whole set has 6 tabs for labels. The tabs are 13 mm deep x 50 mm wide and compatible with most label-makers including popular Phomemo and Brother devices.

The 3 nodes protruding from the tray keep the pages lodged in place. They're also hollow, making the trays modular - stackable in whatever order you'd like (see the video). Be careful to pick up the trays on the sides with both hands as shown in the video; there's no better place or way to pick them up.

I kept 'colors' off the listing since this is whatever colors you want re: filament. It's worth noting that the label tabs, the frames, and the hollow nodes all have different heights so you could slice them for color changes - fun!

3D Printing Details/Recs:

* The zipped folder has a master project .3MF file with all 12 pieces (6 tiles, 2 tab variations on the bottom 3 tiles = 12 pieces) that are labeled: "BL A" means Bottom Left with the tab on the left - or A - side; "BM B" means Bottom Middle with a tab on the right - or B - side, etc. The zipped folder also has 2 subfolders: "All Trays Different Colors" and "All Trays Same Color" with STLs named in ways that'll help you depending on how you want to print.

* As seen in the pics and video, one tray is made up of 6 interconnecting pieces. Feel free to glue to reinforce, but I haven't needed to do that. They fit snugly together.

* Each piece of the tray is a 1 hour print, which I love because if the print fails you didn't lose any more than an hour. Each piece is about 10 grams, so a tray takes approximately 60 grams of filament. All 6 trays comes to 360 grams of filament.

* Only tested/shown material is PLA, .2mm, infill 15%

* They print fine without supports but I print them with supports on build plate only because the undersides of the connector tabs are tidier.
