My model doesn't load

I have a problem with a model i want to implement, my mod already has quite a few models and All of them are bigger than a block, but i made this model

As you can see is 2 blocks large 1block hight and that little part back there that is like 0.6 blocks high

As i said my mod already has quite a few models all of them bigger than a block in X-Z but this is the first bigger than Y, but even with that i am making another mod with models biggertthan 1 block Y and they load correcly.

I put the model and the textures and Set the collision box to (-1D,0D,0D,1D,1D,1D) the material is wood the name is Working Bench and i have it in decoration, but when i build and run it appears the no texture block (Purple & Black). and it desnt matter if i dont change the collision box, it doesn't load.
