the model is good and just need some modification on the bottom of it,the model is hollow and you need open a connective hole in the date file ,generally speaking ,it it not bad!
Unable to convert file as requested so had to pay some else to repair the file. His response (I am sorry but I cannot modify the model . The source file I made was on my hard drive that got damaged long time ago. The only file is this decimated stl file. However I tested it on FDA printer as well and it turned out great. Just needs to have supports added in the slicer and of course , being scaled up which is also possible in any slicer).
i've bought it,it is hollow and the model is good ,just need to open a connective hole by yourself
