Dual Slider Buckle for EyeSeal Mask head strap

thingiverse

If you experience nocturnal lagopthalmos and wear an EyeSeal mask to keep your eyes moist while sleeping, you might find the factory cloth head strap to be less than ideal. I created a better head strap using 1/2-inch sewing elastic and two slider buckles that I printed in TPU. The photo shows the head strap assembled. Print them with 100% infill. Materials other than TPU would probably work well too. TPU simply mimics the flexibility of the two single slider buckles that came with the mask. This setup keeps the mask more secure and prevents the horizontal strap from sagging down to your ears, which can be uncomfortable. I am not associated with eyeeco.
