Under desk drawer system. Screw the runners under your desk, choose a version of drawer to print and slide it on the runners. Standard drawer dimensions 200mm long, 120mm wide, 60mm deep. Designed so no supports are needed when printing. I have allowed a little bit of play between runners and drawers, so it doesn't "stick" when opening.

Good for storing small items (pens, paper clips, staples, etc) to keep your desk tidy.

drawer-v1 = no divider (single partition) - black/purple photo
drawer-v2 = width divider (two partitions) - black/yellow photo
drawer-v3 = length divider (two partitions)
drawer-v4 = width and length divider (four partitions)

-extra-large.stl, drawer 350mm long, 200mm wide
-half-height.stl, drawer approx 30mm high
-mini, drawer 150mm long, 150mm wide
-wide, drawer 150mm long, 200mm wide

Runners v2: These are 1mm shorter than v1 allowing for a tighter fit of the drawer to runners. So... v1 runners have 1mm clearance each side, v2 runners have 0.5mm clearance each side. If your printer settings are dialed in well you should be able to use v2 and have the drawers slide firmly but freely. Alternately if you print at higher than 0.2 resolution and/or larger than 0.4mm nozzle you may want to consider v1 runners.
