We have a 3-year-old Nylex 12mm x 30m Auto Retractable Hose Reel and the hose guide that moves left to right so that the hose rewinds in a useable manner broke. Nylex do not sell these parts and the only thing they suggested was to buy a new hose - at $199.00 that was not going to happen.

I created the original model weeks after venturing into the 3D printing realm and the fix is rudimentary, but it works. At the time I had not worked out how to completely dismantled the broken part to then remodel a full piece, so I modelled what would fit around the existing part.

This has worked for a few months and then I noticed that something had cause it to jump off the track and the pieces where going to break to correct that, so I modelled a wider guide (this model). The only additional item that is required is a bolt and nut to screw it together - and I am sure that it could be printed too, I just happened to have the right one that I could use.

Use ASA and Supports.
