This is a 1/10 scale DELTA 8" benchtop grinder which is the perfect accessory for your RC scale crawler or drift car garage diorama. Place it on a stand or on your workbench and some credibility to your scene. As this is a one-piece 3D printed model, there are no moving parts and you will need to finish the model by painting it to your liking. and adding a couple small pieces of Lexan to the open frames might be a nice touch as well. To reduce material and printing time, the backside has been hollowed out and it open, so heads up!
