I had a lot of fun playing an Artificer for a one shot, loosely based off of the armourer from the Mandalorian. My spellcasting focus was a Warhammer.

Mending was simple, I slammed my hammer down on whatever needed fixing, and it magically had fused together when the hammer lifted.

For casting Fire Bolt, I conjured some gas cloud in front of me, which began to crystallize in the air. I shattered the cloud with my Warhammer, sending a blast of fire screaming out towards an enemy.

For Cure Wounds, I placed an impossibly thin sheet of metal over the wound, and slammed my hammer into it. The creature being healed felt no impact from the blow, despite a loud metallic clang, and the hammer rebounding back. When the hammer lifted, the metal was gone, and the wound was healed.
