This is a popular DIY waist-level viewfinder originally made from cardboard. I upgraded the casing using a 3D printer, improving its design by adding features such as a hot shoe mount, a lid, and a support structure — all of which enhance stability and durability.​​

We have currently upgraded to the third generation, with specific details showcased in the video. The new version features added screw fixation and three-sided light shielding, while more iterations with updated designs are on the way. Moving forward, we may consider incorporating camera adapters for direct connection to cameras. However, due to varying compatibility across different camera models, we will need to explore more practical solutions. Thank you all for your support!（目前升级到了第三代，具体如视频所示，增加了螺丝固定以及增加了三面遮光可使成像更清晰更舒服，加量不加价！还有更多版本等待更新设计。后续或许可以增加上与相机的转接头可以直接连接相机，但因各个相机适配不同，还需参考更实际的方案，感谢大家支持。）
