14th level Artificer (Magic Item Savant) + Metamagic Adept items to regain sorcery points

Considering a 14th level artificer with the Metamagic Adept feat in D&D 5e:

• I’m assuming that the feat does not grant the ability to restore sorcery points by expending spell slots (since it doesn’t grant the Flexible Casting feature)
• It seems to me that an artificer could use the Bloodwell Vial to regain the sorcery points when they roll a Hit Dice, but they would only regain 2 (since that’s their maximum amount)
• Are there other items/ways to regain expended points?

Thanks!
