Lm8uu linear bearing (w/ spheres) customizable!

This is a lm8uu linear bearing w/ a compartment for spheres (in this one each compartment admit 7 spheres with 2,4mm radius)

includes a .skp for customizing ( i thing this sphere is not well done, u cold do another or simple buy iron spheres and customize the bearing block and the block holder)

u will need 8 m3 bolt x 10 mm ( at least 4 m3 to both sides)
and u will need at least 28 spheres (in total u need 63)

(i dont have a 3d printer yet but i think this bearing should work well)
