LM6UU grease tool for luer lock syringe

I needed a grease tool for my Ultimakers' LM6LUU bearings (the 35mm long version of the LM6UU).

I enjoyed @gezatata_269121 's version of the LM8UU tool but could not directly shrink it as the greasing holes would be too small, so I made a combination with @DockGuy 's tool with larger holes to make it work.

A standard LM6UU version, and others with screw cap will follow.

I printed it on the UM2+, but it really needs some grease so it may look ugly. I will give a Try on the MK3S+.
