This provides a way to silverware together, vertically on a shelf or in a cabinet. Print with the flat, slotted surface on the bed.

The number of slots to put silverware in, and all dimensions are parameterizable, using openscad:

silverwareHolder(numL, numW, topThick, baseHeight
, outerPadL, outerPadW
, cutoutlength, cutoutwidth
, lPad, wPad)
numL(W) is number of slots long (wide)
outerPadL(W) specifies the distance from the borders to the slots
cutoutlength(width) dimensions the slots themselves
and l(w)Pad determines padding between slots
