Nút chặn bowden tube cho Polydryer

The tube that comes with the polydryer is too long and thick imo. I also did not want to cut them, so i used a a piece of bowden tube but it kept slipping out. So i came up with this, you just shove the tube in (giggity) and use the blocker on the inside as pictured.

Use a heat-resistant material as it will be inside the dryer.

No supports needed.
