So, we need to look at the non-resident filing requirements for each of the three states.   I will go in the order of your question.

Maine

... , a nonresident individual present in Maine for business for no more than 12 days and earning no more than $3,000 from business activity in Maine is not required to pay a Maine tax or file a Maine return on that income.  See: Maine NR  

Massachusetts

 If you're a nonresident with an annual Massachusetts gross income of more than either $8,000 or the prorated personal exemption, whichever is less, you must file a Massachusetts tax return. You are an individual nonresident if you are neither a full-year or part-year resident.  See: Who Must File a Massachusetts Personal Income Tax Return 

Vermont

You must file an income tax return in Vermont:

• if you are a resident, part-year resident of Vermont, or a nonresident but earned Vermont income, and

• if you are required to file a federal income tax return, and

• you earned or received more than $100 in Vermont income, or

• you earned or received gross income of more than $1,000 as a nonresident. See 32 V.S.A. § 5861 and § 5823(b) (1-6) for information on sources of income.

See: Who Should File 

So review these carefully and see if you meet the thresholds for filing.

Thank you for the question @laurensaltman
