For the easier application of static grass on the model of railway, I created a model of grass applicator. For more details, check the article: https://blog.prusaprinters.org/3d-printed-railways-size-h0-187/
Everything was printed on Original Prusa I3 MK3S printer from Prusament PLA material. You can use presliced gcode with all the parts on one plate or each part separately. You can also customize settings in PrusaSlicer using the 3MF file.
The strainer was printed with the help of modifier in PrusaSlicer with 0 bottom and top layers and increased grid infill to 25%
