About this 3D model

Hi! Need some shelf brackets and Thingiverse has a lot but.....i want something mechanic, steampunk like and easy to print. Made with 123Desing using the Gears provided from examples. I've uploaded 3 designs: A one-nail-hole, other with 2 holes (i used 2 hooks for this) and another with a full gear from behind. Also included the 123Desing file. Use as you wish, feel free to made your own modifications. Hope you find it useful (Mazinger not included) Have Fun!
