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 finalno 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.
