Hose Clip with tooth, ⌀8mm and up, Reusable! Cable Management

Printed mine in PETG on the Core One. I found you can scale it to any size and it works great. I'd advice increasing the Horizontal Expansion to .1mm if you are in Cura (PrusaSlicer it's the XY size compensation under advanced settings). If you want a tighter fit, increase this value, if you want it more loose, lower the value. Adjust accordingly to your liking.
