My faucet broke and the maintenance also replaced a perfectly working hose with a longer one so that some of it sat on the floor. Instead of buying a new shorter hose I made a thing to make a loop on the hose to make it shorter.
A few STLs provided for a few OD hoses. STEP file for 13,5 mm. Fusion360 file is hopefully parametric, only tested a few sizes. Parameters listed in screenshot.
Supports from build plate, use all walls. Only tried PETG, it has good flex to it.
