About this 3D model
Summary I took the original design and thickened the outer edge for strength. I also made the gap the band fits through smaller (4mm). I made these changes for peace of mind as I work at extreme heights as a Wind turbine Technician. The clips didn't clip in as securely as I was hoping on my specific model of hardhat so I also used a few drops of superglue as well. Edit: the clips have stayed securely on my hard hat as of late 2023 with almost daily use Print Settings Printer Brand: Creality Printer: Ender 5 Rafts: Yes Supports: No Resolution: 0.2mm Infill: 100 Filament: Spool 3D PLA Black
