About this 3D model

My dad and I really loved the older 89' batman and i was looking for his logo to make as a gift for my dad. so i did a little search on thingiverse and found one made by gvigil90. i thought it looked perfect the only thing it was missing was that class oval around the outside. so i just modded it a bit and to get it closer to what i was envisioning and Valhalla here it is. thanks gvigil90
