OK so I bought some organizer/drawers from my local supermarket under the Workzone brand.
With 33 drawers able to have 2 dividers each I was upset that only 1 per drawer was provided.
So I thought, heck - this is why I bought a 3D printer.
Printed in PLA, 0.2mm layer, brim and support (as it's printed upright), 15% infil (not that there is anywhere to infil).
Snap the support off and fit it into the drawers.
