I remixed JomMa's thick spacer tile into a 1 tile bridge so you can add a support using an existing column. It can be placed at any height, just like a spacer.
As this introduces leverage, you will need to be cautious to not tip over the column. To counteract you can balance it out with another bridge to the opposite side or put 2 marbles inside the empty space to weigh it down.
Supports: No
Resolution: 0.2
Infill: 20%
Material: I've only tested ABS, though the original it's based off used PLA.
The author remixed this model. Imported from Thingiverse.
Converted to a bridge.
