There are two print configuration versions, one for display or non-durable applications, and the other for role-playing or event applications. The non-durable configuration uses a 3% infill and only one wall loop to minimize material usage, as the print pieces are large. This means the print pieces are easily damaged. The durable configuration uses a 7% infill, also to minimize material usage. When you need the print pieces to withstand real-world conditions, such as at exhibitions or in outdoor weather, you should use this configuration.

The text at the top of each block is not accurate, at least according to the information sources I've collected. Its existence is solely to help those who might not know what an ERA block is to identify it and indicate that the ERA block is Russian. I have limited access to information, and I would greatly appreciate it if you could fact-check the shape, size, and other characteristics of the ERA block or provide feedback. Thank you!
