Custom 3D product viewer for a Shopify furniture store

Hi, I’m helping out with my family’s furniture business, which sells handmade pieces through a Shopify store. I’m a software engineer, but 3D isn’t my area, and with the time I have, I’d rather work with someone who already knows it well. Shopify’s built-in 3D viewer works, but it looks pretty generic, and I’d like something that shows off the wood and finishes better, mainly with nicer lighting and a cleaner look on the product page. The important part is that my family can manage it on their own: upload a 3D file to a product in the Shopify admin and have it show up, without anyone needing to touch the code. I have 3D files ready for a couple of products to start with.
