Better use Electrum wallet than Samourai wallet because it's compatible with Ledger nano s just import the ledger nano wallet to Electrum and then you can sweep your opendime private key to Electrum with the Ledger nano.
You can follow the guide how to use Electrum with your Ledger nano from here
Set up and use ElectrumOnce you generated a wallet from Electrum with Ledger nano you can sweep your opendime private key to Electrum. This is the best and safe if you have a big amount of BTC from your opendime.
Or you can import your private key from opendime to Electrum and send Bitcoin manually to your Ledger nano address but for safety I recommend to sweep them directly to your ledger nano with Electrum as suggested above.
