Shroud friction fits into the outer fins of the Waveshare Raspberry Pi CM5 Active Cooling heatsink, as well as passive heatsinks of similar size. Supports 30mm fan (3010): mount holes accept 3mm machine screws (tap directly into the plastic)

Settings I used:

• Sunlu PLA+ 2.0
• 0.20mm layer height
• 5 wall loops
• 4 top/bottom shell layers
• Suppport - 2 Raft layers, 0.15mm z-distance, concentric interface ( you might not need to use rafts, I'm just bad at this >D )
