Return and Refund Policy

Our refund and returns policy lasts 15 days from the shipment of the merchandise. If 15 days have passed since the merchandise left our workshop, we cannot offer you a full refund or exchange.

To be eligible for a return, your item must be in the same condition that you received it. It must also be in the original packaging.

Refunds or returns of 3D prints are not accepted due to imperfections in those areas of the print that have required supports.

3d scans are exempt from return/refund.

To complete your return, we require a receipt/invoice or proof of purchase.


Once your return is received and inspected, we will send you an email to notify you that we have received your returned item. We will also notify you of the approval or rejection of your refund.

If approved, your refund will be processed and a credit will automatically be applied to your credit card or original payment method, within 7 days.

Late or missing refunds

If you haven't received a refund yet, first check your bank account again.

Then contact your credit card company, it may take some time before your refund is officially posted.

Next, contact your bank. There is often some processing time before a refund is posted.
