Chainkeeper (Quick Release)
thingiverse
Chainkeeper to keep your chain taut whilst washing/transporting your bike with the wheel out. Designed for a standard quick release. Whilst you could remove your QR skewer from your bike, and put it through this, you might find it easier to just use an old/spare rear 135mm QR skewer to keep through this. Remove your wheel, and slip the QR with the chainkeeper on in its place, threading your chain through it to keep it taut. I also have a [thruaxle version that this was derived from](https://www.thingiverse.com/thing:6010580).
