Foam board sealer

Inspired by the videos below, I've created this reusable form board sealer tool, so I don't need to cut another one every time I have to seal the edge of a foam board.

**Note that depending on the filament and the glue you use, this tool may not work well for you, because the glue may melt the material or stick to it!**

I've uploaded the model in two versions, which differ in the width of the opening, so you can test which one fits your board the best:
- `Foam board sealer narrow.stl` has 5.00 mm opening
- `Foam board sealer wide.stl` has 5.20 mm opening
