Magnetic hydration hose retaining clip

prusaprinters

This is for ease of access & stowage of a water bladder hose.This clip is designed to attach to webbing of either 11 mm width or 25 mm (1 inch).In my case, I fit it to the webbing present on my Osprey backpack's shoulder straps, which is 11 mm in width.I lost the original one because it was meant for 19 mm or 25 mm straps, & therefore was too loose & fell off.I designed it to be similar to an existing non-magnetic hydration hose clip I already have. Here is the same one on Amazon. You can find these on eBay for much cheaper too.The Inventor file can be trivially modified for any strap width.I bought these magnets. They are 10 mm diameter by 1 mm thickness.
