Is it possible to make money with Fulfillment by Merchant?

Hello folks,

I am trying to start a business with a very small product line I invented. I currently have one listing: https://www.amazon.com/dp/B0CT7SWS1Q

I make the product myself and don’t have a ton of inventory, so I feel like FBM is the right choice for me, but I rarely buy things that are not Prime. I don’t qualify for seller-fulfilled prime. So, is it worth investing my time in selling on Amazon if I choose not to use FBA?

When I used FBA in the past for 3D printed products, it was a nightmare with the amount of returns. Most people don’t expect a 3D printed product from Prime. Are 3D printed products a bad fit for selling on Amazon?
