3D QR Code Generator

Published: Sep 10, 2025

Electro Flevo attracts a lot of attention; people on the street often come up, ask questions, and are interested in the design and principle of operation. However, many are hesitant to approach and ask, although genuine interest is still noticeable. Also, I am often not around the bike to answer questions and share information. A way to provide quick information was needed.

One could simply print a QR code and a link on paper, laminate it, and it would work. However, the aesthetics would clearly suffer, and easy solutions are not our way. A 3D printer caught my eye, and thus a plan was born. A quick search for ready-made 3D QR generators yielded no results, so I quickly sketched my own in Python. The input is data for the QR code, and the output is an STL file that can be loaded into the preferred slicer and printed. Additionally, to host the generator, the first version of this website was created. Alongside this, a simple URL shortener on my own domain was developed, allowing for the QR size to remain reasonable.
