One of the sliders for the chest strap on my Osprey Radical 26 backpack snapped when I tried to adjust it. The slot on the original design is only 16.5mm wide but the strap on my backpack is about 20mm. I scaled up the model to make the slot roughly 21.5mm wide.
According to the original author the clip might also fit other brands than Osprey with a similar design.
