Thank you for sharing an image of your creations! That model looks amazing.
You can definitely sell both your models and your services to make custom models (if you offer that as well) through Shopify. Have you started a free trial store yet or have you sold your models through an online store before?
If not, I would encourage you to use our Getting Started course to guide you through your initial setup and to help you launch: Shopify Learn - Getting Started.
Did you have any questions about launching a store I can help with?
