Rpi cluster

thingiverse

This is an Rpi cluster for 4 Rpi boards. Both Rpi 3 & 4 boards can be fitted. All holder items are the same for the Rpi3 and 4, except the cover is different. The Rpi slides into the rack without touching other Rpi's, so it's a hot swappable cluster ;-) About the airflow: the rack is fully closed to optimise the airflow from bottom to top. The FAN on top is a 12V FAN, working on a 5V USB adapter. My cluster runs K3s. Each cover holds a nice Rpi logo. A Mr. Robot mask on top finishes the design. Printed on a Prusa i3 Mk3s, all in PET, because I prefer PET (it sticks very well). The yellow cover is in PLA, because I had no 4th colour in PET :-)
