CPAP Mask Strap Clips / Resmed Airfit P10

I designed these for my Resmed Airfit P10 CPAP mask, as the headgear/strap gets loose over time as it stretches. Given the price of a replacement, these are a great alternative if your strap is too loose or too large. I guess they can also be used for other similar straps, but will need to tweak the size, either through scaling or editing. Simply post the split part of the headgear through 1 clip for each half of the strap, You can then pull it through to adjust how tight the strap is. I printed on my Prusa i3 MK2 on 0.15mm Optimal Slic3r settings (see pictures). It's not the most finished of prints, but only took 12 mins for a pair of clips.
