Pillarmen from JoJos Bizzare Adventures 3D print model

Good morning ! impossible to avoid the model! the file is very badly designed the rock is hollow when hollowed out but pockets appear everywhere on the rest of the model .... it's an anarchy considering the price .... it should have been designed so that we can hollow out the model on resin printers or specify that it is only for fdm printers .... I will demand a refund because I cannot print it due to the poor design of the file.....!!!
