Sleeve Case for Raspberry Pi 4 with heat sink

thingiverse

I loved Avatar7's remix of the Sleeve Case for older Pi's, which fit perfectly on the new Pi 4B. But I decided to open up some space inside to allow heat sinks on the SoC and RAM. The Pi 4 gets quite hot, making a heat sink an absolute necessity. The main case remains identical to the original except for extra interior cuts, while the end cap stays exactly the same. Initially, I tried modifying the STL file using OpenSCAD, but it couldn't render the result without generating an internal error. Surprisingly, importing the STL into TinkerCAD and making the exact same change worked perfectly fine. Update: Most HDMI-to-microHDMI adapters have thick connector shells that won't fit in the original microHDMI cutouts. So I added a second version of the case with one much larger cutout around the two microHDMI connectors, ensuring most connectors can fully seat. Update 2: There are some discontinuities in the original model that appear as surface cracks when sliced and printed. These may also be why OpenSCAD blows up trying to render it! I filled in the cracks with additional material to make the finished piece look better.
