About this 3D model

An expansion piece based on the backplate created by a big shot, with secondary creation. Suitable for Hikvision's NVMe hard drive box, designed with many hollowed-out areas to address NVMe hard drive heat dissipation. The horizontal mounting method is implemented, and the expansion piece is not very securely attached to the backplate. The hard drive can slide left and right, but it does not have a significant impact. I used PETG with a layer height of 0.2mm, other materials may also be suitable. It takes some force to insert it into the backplate.
