I've made a sword model, textured it and compiled it, the only problem is when trying to create it in game, I get a size error telling me it's too large, probably due to the design (whoops)

The tutorials I followed had size limitations on them (a bounding box), but my blade just fits in it, have I done something wrong?

This is also my first time doing a mod like this, so I kinda expected trouble
