About this 3D model

This is a QNAS4 redesign by 汪汪队射手 from Bilibili. This print model does not have a hard drive cage. The hard drive cage uses the original QNAS4 model. You can download "hard drive cage 20230214.stl" or download the original UP master's model link. Thanks to the UP master for sharing. This model is suitable for the Zhongbai N100 mini host's disassembled motherboard. This motherboard has a USB front panel and the power switch is located on the front panel, so it can only be made L-shaped to allow use of the power button and multiple USB ports. At first, I designed a shape (see image 6), but I found that the wires needed to be forced to reach the hard drive cage below, and because the power cord I bought from a certain online marketplace was too short, the hard drive cage could only be placed upside down, which might be unfriendly to the hard drive. So I redesigned it to the current version. I have zipped the old version's Solidworks file and put it in the attachment. If you need it, you can take it. Based on the original UP master's version, in addition to purchasing the QNAS4's sequential boot back panel, I also bought a 12V PWM fan temperature control speed regulation module. The temperature probe detects the surface temperature of the hard drive to achieve speed control of the cooling fan.
