About this 3D model

Because it is necessary to support a TFOLED display, a long and a short screw have been designed (the short screw is not needed without a TFOLED). Due to the limited printing accuracy of the machine, threads have not been drawn, and it is recommended to use glue directly. The model only supports Raspberry Pi 4B, and the required accessories are as follows: SATA protocol solid-state drive A 4010 specification fan Easy-to-drive USB3 to SATA cable 4 M3.5*5 flat-head screws for fixing the hard drive 4 sets of M3.5*10 screws and nuts for installing the fan
