Needed a riser for the GeeekPi Raspberry Pi 4 case to accommodate a Loverpi isolated PoE hat and would allow the 40mm x 10mm case fan to clear. I added some vents on the side to accommodate the case being on a flat surface with little air flow.
PLA should be sufficient but PETG might be better. Printed with a .4mm nozzle and .25mm layer height.
Update: Added thick version so strengthen the lower part when printed in PLA which is less flexible compared to PETG
