General purpose sign/tag with embedded magnets and editable text

After making a few kitchen and general purpose signs with embedded magnets I decided to create a general purpose model. Maybe someone else could use this.

The model has a cavity for inserting magnets and the 3MF file includes a pause allowing you to do so. I used  2mm thick magnets I had on hand. You can use a slicer to increase the height and therefore cavity depth if your magnets are thicker. The 3MF file also allows you to customize the text. Scaling in the slicer would enable more magnets or longer words.

The slicer may give a warning about supports for the cavity. Just ignore that because the magnets provide support. And the files are labeled for a fireplace because I puts this on our flue to remind it is closed.
