I printed a honeycomb wall for the side of my work bench to utilise some unused space for larger measuring equipment (which otherwise always seem to end up at the back of my bench on castors and not easily accessible) like long rulers, builders squares, etc.
I modified the default empty insert to accommodate a 10mm x 3mm neodinium magnet for securing steel items so they don't fall off when moving the bench.
The author remixed this model.
Some custom (from scratch) to honeycomb wall spec, others modified to accommodate 10mm x 3mm magnets to hold steel rulers and/or squares.
