Magnetic hydration hose retaining clip

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. Non-affiliate link.

2024-04-20: rev 6

• Solidworks 2020 model now

• upgraded to way more powerful magnets

  • 7.92 OD x 3.19 mm height, qty 2

• cleaned up CAD file

  • includes both the part that mounts to the backpack straps & the part that clips onto the hydration hose (designed for 3/8" OD)

• not yet printed

2024-04-25 update

• had to bore the central cavity to 16 mm to achieve easy fit of 2 printed parts together

• hose mounted piece printed on a Form 3 in Durable resin

  • a little loose of a fit

• backpack mounted piece printed on an UM S3 in HIPS filament

  • HIPS seems to be fairly dimensionally inaccurate

2024-05-19 update

• hose mounted piece has too loose of a fit around the hose

• magnets are very strong & very nice, but now the hose simply detaches from hose mounted piece

• magnet embedded in hose mounted piece came out because press fit wasn't good enough

  • I did not glue this in place, but I'll consider doing it next time when I uprev the hose mounted piece

2024-05-20 rev 8

• base piece unchanged

• hose holder changes

  • magnet cavity deepened by .5 mm

  • now attaches to hose via zip tie

    • 2.6 mm width

    • 1 mm height
