Seeed Studio reRouter CM4 Case

I bought the reRouter CM4 from Seeed Studio, but the case was out of stock, so I designed my own. 

This particular board can get pretty hot, so I added a 30mm fan slot to the side of the case and some holes close to where the CM4 should be.

Update (13/02/2024): I've made a few fixes to the mesh files and some minor spacing tweaks and reuploaded the STLs.

Update (06/07/2024): I made a 10-inch rack mount version, grab it here.

Materials

• 8x M2.5 Thread Inserts (4x for the feet, 4x for the cover).
• 8x M2.5 screws 6mm (For cover and feet).
• 4x M2.5 screws 8mm (For securing the CM4 in place).
• 4x screws and nuts for the cooler, but the size depends on your fan dimensions.
• The reRouter CM4.
• A CM4. Take a look at https://rpilocator.com/ to find one.
• Some passive cooling for the CM4, like the one from Waveshare.

Assembly

• Add the thread inserts to the case.
• Install the 30mm fan.
• If you're using the passive cooler from Waveshare:
  • Pop the CM4 into the reRouter.
  • Screw it in using the spacers from the passive cooler, leaving the screw holes facing upwards.
  • Insert the thermal pads.
  • Insert the passive cooler, and screw it in place. It should look like the picture below.
     

• Secure the carrier board into the case by adding 4 M2.5 screws in the bottom.
   

• Connect the fan to the USB3 header (Schematics here)
• Close the case with the other 4 M2.5 screws.
• Install the feet with 4 M2.5 screws.
