Bearing filling cap for Zeller + Gmelin Divinol Grease

This is a cap to pack 8mm linear bearings with grease from a 1kg Zeller + Gmelin Divinol grease tube. It attaches directly to the grease tube, and has outlets inline with each of the four bearing races of common 8mm linear bearings. 000-150 grease is relatively low viscosity and works well for the linear bearings of 3D printers
