Product Description
This is a coaster with a bottle opener. I tried printing a previous version and it worked, but got warped from too much bending, and was thus unstable.
I believe I fixed that issue, and didn't change the geometry of the opener. The opener will work, but the coaster may not be immune to warping or other issues as I have not tried it yet.
Yes, I realize it has holes in it. For most things it should still work to keep your table dry.
