Tevo Little Monster Needle Bearing Idler Pulley

I was perusing a bearing website to locate some high-quality bearings to use for idler pulleys because I'm sick of crunchy bearings. Then I discovered these magical needle bearings tickling my creative mind. Little bit of tinker-cation and I determined the right combination of components to replace the current ball bearing setup with needle bearings! No more crunchiness!
