BOM: Printed with ROSA3D High Speed PLA Dark Blue
This is the V2 (Version 2) update of my decorative nut covers. Based on feedback and testing, I have re-engineered the internal tolerances to ensure a perfect friction fit.
These caps snap securely onto standard metric hex nuts, covering sharp bolt threads and rusty metal surfaces. They are essential for baby-proofing furniture or simply adding a clean, finished look to your projects.
The Set Includes (Standard Metric Hex Sizes):
Small: M3, M4, M5
Medium: M6, M8, M10
Large: M12, M14, M16
Why print V2?
Better Fit: No more loose caps falling off or tight caps cracking during installation.
Safety: Covers exposed bolt ends to prevent scratches or snags.
Clean Aesthetic: Smooth dome geometry hides ugly hardware.
Printing Instructions:
Orientation: Print flat on the hex opening (upside down).
Supports: None required.
Material: PLA works great. PETG/ASA for outdoor use. TPU is fantastic if you want a rubbery, unbreakable bumper.
