I've put up filament shelving brackets with 1" wooden dowels to store my spools, and wanted some name tags to organize types of filament. I made these up and they are working well for my use. They are multi-colored on the plate, so you can easily change the tag/word colors to suit your needs. If you would like a new specific tag made up that I didn't already make let me know and I can add it.

If you are using different sized rods than I am, you can try scaling them up or down. Scaling up shouldn't be much of a problem, but scaling down with some of the tags with smaller print might start running into issues with letters not printing correctly. If in doubt, scale it and look at your print preview and go from there. I printed mine with a 0.4mm nozzle with 0.2mm layer heights. Scaling down may require a smaller nozzle and/or thinner layer heights.

I printed mine on an A1 Mini, so I kept the speeds a little conservative to make sure nothing tipped over as I'm not using any brims. You can always adjust your slicer settings to whatever you feel comfortable with for faster speeds, adding a brim, etc. If you do not wish to print all of the tags, go into your slicer's object section and delete ones you don't want.
