you could... LN in more sats into ecash to bring the amount above what is needed to pay an LN out to your wallet, but fees are not easily calculated so you may end up with more 'dust' (been there myself)

.. or just leave it there, as a goodbye gift for the mint that you just used. The sats are still in the mints LN liquidity, no sats are lost by the mint.

... or you can send them to me ;)
