Last updated: October 24, 2026

At FlowTheory SD, we take pride in designing and manufacturing quality 3D-printed products. We want you to be satisfied with your purchase and understand your options if something isn't right.

1. Standard Product Returns

We accept eligible returns of standard, non-customized products within 30 days of delivery.

To qualify for a return:

The return must be requested within 30 days of delivery.
The item must be unused, uninstalled, and in its original condition.
The item must include all originally supplied components.
Proof of purchase or an order number is required.

To request a return, please contact us through the contact form at https://flowtheorysd.com/pages/contact.

Do not send items back without first contacting us for return instructions.

2. Custom-Made and Personalized Products

Because many FlowTheory SD products are manufactured to customer-provided specifications, custom-made and personalized products are not eligible for discretionary returns or exchanges.

This includes products specifically designed or modified for:

A customer's exact speaker make and model.
Custom speaker mounting dimensions or configurations.
Personalized designs or special requests.
Other customer-specific manufacturing requirements.

Products manufactured to a standard, publicly offered specification are not automatically considered custom-made simply because they are produced after an order is placed.

Custom-made products remain eligible for applicable remedies if they arrive defective, damaged, incorrect, or otherwise fail to meet legal requirements.

3. Damaged, Defective, or Incorrect Items

Please inspect your order upon delivery.

If you receive a damaged, defective, or incorrect product, contact us as soon as reasonably possible through our website's contact form.

Include:

Your order number.
A description of the problem.
Clear photographs of the item and packaging, if available.

We will review the issue and, when appropriate, arrange a replacement, repair, refund, or other remedy.

We cover reasonable return shipping costs when a return is required because of our error or a qualifying product defect.

Nothing in this policy limits any rights or remedies available under applicable consumer protection laws.

4. Speaker Adapter Fitment

FlowTheory SD manufactures automotive speaker adapters for specific vehicle and speaker configurations.

Customers are responsible for providing accurate vehicle information, speaker make and model, and any requested measurements.

We encourage customers to confirm compatibility before ordering.

If an adapter is manufactured according to incorrect customer-provided specifications, it generally will not qualify for a discretionary return when it is custom-made.

However, if we manufacture the adapter incorrectly, provide inaccurate product specifications, or supply a defective product, we will work to resolve the issue.

Modification or improper installation may affect return eligibility, but does not automatically eliminate applicable rights relating to product defects.

5. Return Shipping Costs

For eligible standard-product returns made because of a change of mind:

Customers are responsible for return shipping costs.
Original shipping charges are generally nonrefundable unless required by law.
We recommend using a trackable shipping service.

For qualifying defects, incorrect items, or errors caused by FlowTheory SD, we will cover reasonable return shipping costs when a return is necessary.

6. Refund Processing

Once we receive and inspect an eligible returned item, we will notify you of the refund decision.

Approved refunds will be issued to the original payment method, unless otherwise agreed or required by law.

We generally process approved refunds within 5 business days after completing the return inspection. Your bank or payment provider may require additional time to post the funds.

If your refund has not appeared after a reasonable processing period, please contact us.

7. Exchanges

For eligible standard products, please contact us to discuss an exchange.

Custom-made and personalized products are not eligible for discretionary exchanges, except where required by law or where we agree to provide a remedy for an issue with the order.

8. Order Cancellations

Please contact us promptly if you need to cancel an order.

Standard products: Cancellation requests may be accommodated before shipment.
Custom-made products: Cancellation requests may be accommodated before production begins. Once custom production has started, cancellation may not be available, subject to applicable law.

If an order has already shipped, the applicable return provisions will apply.

9. Natural Characteristics of 3D-Printed Products

Our products are manufactured using additive manufacturing technology.

Minor cosmetic characteristics, including visible layer lines, slight surface texture differences, and small variations in finish, are normal aspects of 3D printing and are not necessarily defects.

These characteristics do not excuse material manufacturing defects, incorrect specifications, or products that fail to meet applicable quality requirements.
