BOM: Printed with ROSA3D High Speed PLA Gray
This is an updated "Version 2" of my printable nut inserts, designed specifically for 40x40 T-slot aluminum extrusion profiles (standard 8mm or 10mm slot width depending on the manufacturer).
What's New in V2? These inserts are slightly longer than the previous version. The increased length provides better surface contact with the aluminum channel, ensuring the nut stays perfectly perpendicular and does not twist or rotate while you are tightening the bolt.
The Set Includes:
M3 Insert
M4 Insert
M5 Insert
Key Features:
Anti-Rotation: The extended body prevents the nut from spinning inside the slot.
Secure Fit: Designed to hold standard hex nuts firmly.
Cost Effective: A quick alternative to waiting for metal T-nuts to arrive.
Printing Instructions:
Orientation: Print flat on the widest face.
Supports: None required.
Material: PETG or ABS/ASA recommended for structural parts, though PLA works for light loads.
Walls: 3-4 perimeters for strength around the nut pocket.
