Bouillon cube dispenser for cabinet doors, 1 to 6 rows

Gets bouillon cubes off the shelf and onto the inside of a cabinet door, where you can see them. Each row is its own open-topped slot, with a curved cut at the bottom so you can slip a cube out. Change the rows and the cube size to match your brand.

Parts

  • dispenser · PLA · Upright on its flat bottom, as modelled; no supports

    84.8 x 29.8 x 99 mm at the defaults, about 47 g and 1 h 15 min at 2 walls / 15% infill. PLA is stiff and easy for a dry cupboard; use PETG if the cabinet sits over a stove or kettle.

  • fit-gauge · PLA · Flat on the bed

    Optional, only when 'Also print a fit gauge' is on: an 8 mm tall slice of one channel with the same clearances, about 3 g and 8 minutes. Your cube should drop through flat under its own weight but not turn sideways.

Notes
Engine estimate at the defaults on a Bambu A1: about 47 g and 1 h 15 min at 2 walls / 15% infill (about 65 g and 1 h 45 min at 3 walls). Print upright as modelled: the mouths narrow at 45 degrees into the sight slots, so there are no long bridges. 6 rows (243 mm wide) or 25 mm thick items at 8 per r

Hardware

  • 2 × 3 mm countersunk wood screw, 10-12 mm long · Through the two holes in the top of the back panel, driven from the front. On a typical 18 mm door a 12 mm screw goes about 9 mm into the wood; keep the length under the door thickness plus 3.2 mm so
  • Double-sided mounting tape · Alternative to screws on the flat back. Its hold is not checked by the engine.

Assembly

  1. Measure one cube (width side to side, depth front to back, thickness as it lies flat) and set the three Item sliders, the Rows and Items per row.
  2. Optional: turn on 'Also print a fit gauge' and print the ring first. The cube should drop through flat but not turn sideways; if it sticks, raise 'Clearance around the item'.
  3. Print the dispenser upright with no supports.
  4. Hold it against the inside of the door where it clears the shelf edges when the door closes (it stands 29.8 mm off the door at the defaults). Drive two 3 mm countersunk wood screws through the holes in the top of the back panel from the front, or stick it on with double-sided tape.
  5. Load cubes flat from the top, above the front wall.
  6. To take one, put a fingertip up into the slot in the floor, lift the bottom cube slightly over the 1.2 mm front sill and slide it forward out of the mouth. The cube above stays behind the front wall and drops into place.

Good to know

  • Designed and checked in the Loftsmith engine, not printed or tested. Wrapped cubes vary in size, so print the fit gauge first.
  • Not every combination of sizes works. Each slider end passes with the others at their defaults, but very wide, thin items (for example 60 x 8 mm) get too little room to slide freely, and flat tea-bag envelopes under 8 mm are outside the range; the Check tab shows a failing check.
  • The fingertip check models a 16 mm rigid fingertip and estimates the push from an assumed cube density of 1.2 g/cm³ (about 1.1 N for a full default row). Real cubes, friction and fingers differ; a very tall row of heavy items can exceed the 5 N limit and the check will say so.
  • The 1.2 mm sill keeps the bottom cube in when the door swings; a hard slam was not simulated.
  • PLA softens around 55 C. Near a stove, kettle or dishwasher steam, print it in PETG.
  • Mounting-tape hold and screw pull-out were not checked; use screws for 4 or more rows or tall stacks.
