Terms of service
The Lucky Printer Co. LLC, Massachusetts. Last updated November 11, 2026.
These terms apply when you ask for a quote or order a 3D printed part on this website. By uploading a file or placing an order you agree to them.
1. Who can order
You must be at least 18 years old and able to enter a binding contract. We ship to addresses in the United States only.
2. Your files and the rights to them
- You confirm that you own each design you upload, or that you have the right to have it printed.
- You are responsible for any claim that a part we print from your file infringes someone else's patent, copyright, trademark or other rights, and you agree to cover our costs if such a claim is made against us.
- We use your files only to quote, review and print your order. We do not sell them or use them for anything else.
3. What we do not print
- Firearms, firearm parts, frames or receivers, magazines, suppressors and any other weapon or weapon accessory (including items covered by Massachusetts General Laws c.140, sections 121C and 121D).
- Logos, emblems, badges, brand marks or licensed characters, unless you hold the rights to them.
- Anything illegal to make, own or ship where you or we are located, and anything meant to hurt people.
- Safety-critical or load-bearing parts (see section 4).
File names are screened automatically. Weapon words are refused; logo and brand words hold the order for Lucky's review. A match never approves an order.
4. Not for safety-critical use
Our parts are printed in plastic (PETG and TPU). They are not rated for safety-critical or load-bearing use, including brake, steering, suspension or seat-belt parts, helmets, child seats, climbing or lifting gear, medical devices, or anything whose failure could injure someone. Do not use them that way.
5. Quotes, review and payment
- The exact price comes from slicing your file on our print farm's computer. The instant estimate shown before that is only an estimate. A quoted price is valid for 7 days.
- Every order is reviewed by a person and may be refused before any charge.
- At checkout your card is authorized, not charged. The amount is captured (charged) only when Lucky approves the order.
- If an order is not approved within 48 hours, the authorization is released and you are not charged.
- If we refuse an order, we release the authorization and tell you why.
- Massachusetts sales tax (6.25%) is added at checkout for Massachusetts addresses, on the price only (shipping is not taxed). Shipping is charged as shown at checkout.
6. Shipping
We give you a ship-by date at checkout. Delivery times depend on the carrier. Tell us right away if a package does not arrive.
7. Broken or wrong parts
If a part arrives broken, or is not what the file and the order describe, email us within 14 days with photos. We will reprint it or refund it, once per order item. Fit and function in your application are your responsibility: please check your model's dimensions before ordering.
8. Limit of liability
To the extent the law allows, our total liability for any order is limited to the amount you paid for that order. We are not liable for indirect or consequential damages.
9. Governing law
These terms are governed by the laws of the Commonwealth of Massachusetts.
