In Line Wire Connector With Strain Relief and Cover.

thingiverse

Connect 2 wires securely with a 6-32 flat screw like those used to attach computer hard drives, ensuring printed threads hold at layer heights below .2 mm for maximum reliability. The recommended maximum size is about AWG 22. Avoid overtightening the screw, as excessive force can easily damage the wire by clamping it too tightly. To utilize, strip approximately 3.8 inches from both ends and twist them together firmly. Next, insert this joined end into a hole on the side of a round component until fully seated. Then, secure the 6-32 flat screw in place before installing an insulator/strain relief, directing the wire ends to emerge as shown for complete integrity.
