Slanted Gridfinity pen rack sized to your drawer height

Keeps your pens lined up in the drawer instead of rolling around loose. Five rounded grooves at each end hold them at a slant, so you can see and grab the one you want. Change the pen length and thickness to match yours.

Parts

  • pen-rack · PLA · Feet down on the bed, as modelled

    Default 83.5 x 167.5 x 33.3 mm (2 x 4 grid units): about 55 g and 1 h 19 min at 2 walls / 15% infill, no supports. PLA because it is a stiff, room-temperature desk organiser carrying only a few pens.

Notes
Default size: about 55 g and 1 h 19 min at 2 walls / 15% infill. With 3 walls / 15% it is about 72 g and 1 h 43 min. Print feet down; the 45 degree foot chamfers and the rounded tops of the supports need no supports.

Hardware

  • 32 × 6 x 2 mm disc magnets (optional) · Only if you turn on the magnet holes option: 4 per grid cell, 8 cells at the default size. The holes are 6.5 mm across and 2.4 mm deep; glue the magnets in if they are loose.

Assembly

  1. Measure your drawer's inside height, from the floor to the underside of whatever is above it, and set the Drawer inside height slider.
  2. Set Bin bottom above drawer floor: about 0-0.5 mm for a plain open Gridfinity baseplate, more if your baseplate has a solid floor or magnets under the bins.
  3. Measure your longest and thickest pen and set Pen length and Pen diameter; the rack picks its depth in grid units and the slope.
  4. Print feet down with no supports, then drop the rack into the baseplate with the low front cradle towards the front of the drawer.
  5. Lay each pen tip-first into the front cradle and down onto the rib. To take one out, pinch its raised end behind the rib.

Good to know

  • The slope leaves 3 mm between the highest pen end and the drawer top at the height you enter. Measure the drawer's inside height carefully; an error of a few millimetres uses up that margin.
  • The foot profile is checked on the model against the Gridfinity dimensions (42 mm grid, 4.75 mm profile), but fit in a real baseplate is not tested. Print one and try it before printing several.
  • Each foot's 45 degree chamfer continues from 4.75 mm up to 7 mm so the gaps between feet close cleanly. This sits above where baseplate ridges reach, but it is not the standard bin shape above the shoulder.
  • Grooves are 1 mm wider than the Pen diameter setting. Pens with a clip or a fat cap are held by the barrel and may sit higher at the clip.
  • Pens need to be at least about 100 mm long so they reach from the front cradle to the rib. Very short pencils or stubs will not sit on both supports.
  • In tall drawers the slope stops at 25 degrees, so the pens stay lower than the drawer allows. At 4 units wide the rack is about 109 g and 2 h 29 min.
