Garden Hose Entry - common diameter and Gardena's sprinkler system

I've created this modal to create a nice and semi-watertight entry point for a garden hose, mounted inside a wooden shed. See pictures for more details.

I've created this modal to accommodate hoses from Gardena's Sprinkler system as well as default hose diameters. Can be easily mounted and secured with M4 bolts (if I remember correctly; been a while since I mounted them)
