Panel Hole Plug, 3/4" / 19mm

thingiverse

This fits any 1/2 inch / quarter-inch hole in sheet metal. I printed this example in 3DXTech polycarbonate but most other materials should work fine. This is for the specified size hole, not for covering a hole made for conduit or pipe with that size diameter, the actual hole size for those is larger. Maybe look elsewhere for those. I included the original solid models so you can make your own variations. If you post files to this or similar sites, please include your original source files and STEP exports. I've seen several people lose their original files eventually and that makes it harder to create quality files of modified versions.
