CWWK/TOPTON N100/N200/N305 M.2 Carrier board mounting bracket
Description
I bought a CWWK N305 mini PC to make as a small Proxmox/PFSense build, while hosting some VMs and Containers (HomeAssistant, Frigate, etc.). One of the issues I noticed with the M.2 x 4 carrier board that came with the machine was that it 'flopped' around, and wasn't securely mounted to the chassis. I wasn't satisfied with having the board be unsecured, so I took some measurements and made this bracket. With it, the carrier is rigidly mounted to the rest of the system. This design relies on replacing two of the 4 screws holding the mainboard in with 6mm M3 standoffs. While this could've been designed to need no extra parts, I prefer this design as it allows the removal of the carrier board without removing half of the fasteners, potentially affecting the direct-die CPU mounting pressure. If you really want to, you can download the included F3D or STEP file and modify the length of the bracket to reach the extra 6mm required to use just screws. Just keep in mind you may want to use at least PETG as the screws will be ~CPU temp as this is a passive cooler, and the glass transition temperature of PLA is only ~60C. This may lead to deformation of the the bracket, affecting CPU mounting pressure... yada yada you get the idea..
