Xtool M1 Ultra .4mm Felt Tip Sharpie Adapter

An adapter piece for the Xtool M1 Ultra to use a .4mm felt tip sharpie specifically. I am working on an adapter for4 regular .4mm sharpies but the design isn't ready yet. I will update this description when the other design is uploaded. Use this adapter with the same module you use with the Xtool branded pens.
