Quizcen Policies
Last Updated: 04/01/2026
Quizcen is my personal alias — a small one-man airsoft design project run by Kristoffer Marnø (Denmark).
I’m not a registered company, and I’m not affiliated with any airsoft brands or manufacturers. Everything here is built, tested, packed, and shipped by me.
This is a passion project that keeps growing and changing over time. Because of that, I reserve the right to update or change these terms, discontinue products, or stop updating files at any time without notice.
All items are made-to-order, so nothing sits on a shelf. That means no stock, no big factory — just a workbench, a printer, and a lot of late nights.
Digital Products (STL Files)
STL files and other digital items can be bought on Cults3D, BuyMeACoffee, or directly on Quizcen.com — all with secure payment options.
Once purchased, digital products are final — no refunds or returns.
All files are for personal/private use only.
You may 3D print and share photos of your builds, but you may not resell, share, modify, or redistribute the digital files or printed models.
Quizcen’s designs, documentation, and images are protected by copyright.
EAS 2.0 License Terms (Based on Cults – Private Use)
License: Private use only. By downloading any STL files provided by Quizcen, you agree to the Cults – Private Use license and the additional restrictions below.
Cults – Private Use (original meaning):
You are authorized to:
Print and use the 3D prints of the 3D model for private use;
Share images of your 3D prints of the 3D model on communication media such as social networks or websites.
What is not allowed (Cults):
No commercial use or public sharing of the 3D model;
No modification or adaptation of the 3D model for public sharing or sale;
No distribution, sale, donation or exchange of the digital files of the 3D model.
Additional Terms (important):
You are NOT allowed to resell the STL files in any way, including printed parts, assembled units, kits, bundles, or “printing as a service.”
You may not upload, share, repackage, or redistribute the digital files (STL/STEP/OBJ/3MF/etc.) in any form—free or paid.
You may not share or publish modified/remixed versions publicly (free or paid).
If you want to become a reseller, contact me on Discord to obtain a separate reseller/commercial license.
No written permission = no commercial rights.
Failure to comply with these obligations will automatically revoke the rights granted by this license.
General

Products
All Quizcen products are made-to-order and tested before shipping.
Unless otherwise stated, there is no warranty. If a warranty exists, it will be clearly listed on the product page/description.
Minor visual differences or print marks are normal—this is the nature of 3D printing.
Always check compatibility and wiring before use. Incorrect connection may damage your equipment.
All items are made for hobby and airsoft use only. Use at your own risk.
Quizcen isn’t responsible for damage caused by incorrect installation, misuse, or modification of any product.

Shipping partners: UPS, GLS, and Local Tracked Letter.
UPS: Includes full shipping warranty (loss or damage covered).
GLS: Fully covered shipping warranty within their service area.
Local Tracked Letter: Cheapest worldwide option, but no delivery warranty.
Orders are usually shipped within 5–7 working days, depending on queue and print time.
International delivery times vary — customs or import delays are outside my control.
Payment
All payments are handled securely through Shopify Payments.
I never see or store your card details.
If something fails during checkout, contact me before reordering to avoid duplicates.
Warranty & Liability
Unless it’s written in the product description, no warranty is provided.
All boards and parts are tested before shipping and may include a unique serial number for identification.
Quizcen products are provided as-is.
Use at your own risk — for hobby and airsoft purposes only.
Quizcen is not responsible for damage to replicas, electronics, or property resulting from improper installation, wiring, or use.
Batch & Custom Orders
If you want to place a larger or batch order, please contact me first at [email protected].
We’ll figure out details like production time, packaging, and shipping together before confirming the order.
Legal

I usually reply between print jobs and prototype tests—so please be patient. I also have a full-time job, so responses can take a bit.
