Summary

4" Popping cork. I saw 2 other ones on here that were glorified triangles so I wanted to design one that looked and works closer to the real thing. This one has a cupped top. Use supports and print wide end down (should be oriented correctly already). I would use 2 walls (for strength and water tightness) and minimal infill, around 5-10%. I have not printed or tested this yet, so feedback is encouraged and I will update as needed. Use whatever filament you want, And let me know what works best. Center hole diameter is .2" or 5.08mm.
