About this 3D model

Yup, just another simple design for my CR-10 3D printer. This is a cover that make for Y-pulley at the in front of the CR-10 printer. Before I design this cover, I do have another design is for the X-pulley which is cover the belt roller near to the stepper motor. https://www.thingiverse.com/thing:2475990 Some of them print it with 101% and it will be nice to fit on. (I'm print it at 100% scale) For this Y-pulley cover you could have this problem too, so I suggest if you found is big (in between 0.5-1.0mm), scale it to 101%. Thanks~
