Sleeve Case for Raspberry Pi: Heatsink Edition

thingiverse

After using the excellent [sleeve design](https://www.thingiverse.com/thing:604915) from [walter](https://www.thingiverse.com/walter), I noticed adding heatsinks to the Pi (at least Pi 3 B+) would prevent the sleeve from fitting due to clearance issues. This remix simply adds space for the cpu heatsink, specifically the dimensions of ones provided by popular Pi kits by CanaKit. I didn't want to raise the height of the entire sleeve as I think that would diminish much of its aesthetic appeal. Instead I cut out some of the roof above where the heatsink needs to slide in similar to how the original design had done for the Pi 3 POE pins. This is specifically designed for the Pi 3 B+ so I don't know if it will work with heatsinks on other models.
