I print these for our lab in CPE+ so we can dishwash them at 85 degrees C It also works fine in PLA. This design is a bit tricky to print because of the thin mesh. It is important to make the layer height exactly 2mm (Including 1st layer!) so the X and Y directions of the mesh print on their own layers, otherwise the slicer will try to make tiny squares which will fail, instead of long criss-cross.
