Nonbinding Y bushing

This is a redo for a linear bearing holder. But wait you might ask, where is the bearing? A: those bearings are horrid to the point where a block of plastic is better, but these have a hook so that your table wont fall off when you move your pinter.
Only use this on one of the rails, the other needs a full-grab bearing.
Your rail should be centered in the hook, this gives the rail space to move around if your rails are not PERFECTLY parallel, matter a fact, with these, you dont even have to be close. The table will follow the OTHER bearing (not one of these)
Your rails still need to be on a plane tho.
