mindray Bene Heart D30

I don't know why the texture still doesn't show up after I uploaded the.mtl file. Also, the number of model faces might be abnormally large because I haven't optimized the redundant faces... In order to create an OC, I directly modeled a manual defibrillator. This model is designed for the animation of "Minecraft", so... it looks very "square". My native language is not English. I use translation software to translate what I want to say, but I'm not sure how it will be translated... I don't know.
