Chất độn/phích cắm điện - 1/2 "đến 2"

Options provided for ½", ¾", 1", 1-¼", 1-½", 2" knockout holes. Simple prints that thread together perfectly, use the included nut, thumbwheel, or use your own 3/8-UNC nuts.

Dimensions:

• These are sized for standard KO's, but all dimensions are parameterized and available in the included Fusion 360 archive file.
• Threads are 3/8-16 UNC (Class 1 Clearance) with an additional 2.5 thou removed on every thread face on the stud and nut (total 5 thou if using provided printed nuts). At these dimensions threads run smoothly and the stud attachment fails before the threads do.
• O-ring seats are sized for 25% compression (although the stud will fail before the o-rings are fully compressed).

Special Instructions:

• Prints well with 0.40mm nozzle @ 0.2mm layer height, 15% infill. If you need a tighter seal, print at 100% infill so the stud is stronger and you can tighten it further.
• If you need the best possible seal, consider using RTV silicone or easily compressible foam. The TPU & Nitrile gaskets do compress and seal (as-tested), but cannot be tightly compressed without the printed stud failing.
