Swim Snorkle

This is a center face swim snorkle with a self draining valve. I printed the "snokle" and "headband" in 3d Solutech flexible at speed 2400, retraction 0, temp 210, 0.32 layer height. The remaining parts are PLA.

Snorkle: The pictured unit has 2mm wall thickness at the mouth piece but leaked slightly along the tube due to printing defects. I sealed these with silicone. I increased the wall thickness to 3mm and printed but did not assemble another unit.

Valve: To finish the valve body, I infilled one side with cyanoacrylate and then sanded until smooth with a progression of sand papers. For the mechanism, I tried various printed flaps without much success. I think the small channels that remain after printing allow water to infiltate. I eventually settled on small suction cups from the craft store. A 5mm screw will self tap in the center hole and can be tightly forced through the small center hole in the suction cup. You can control the amount of valve tension wit
