8mm Axis Rod Grease Tube w/Plunger

I created this assembly as I was putting grease on the 8mm rods of my printer using gloves and it would be nicer to have a tool that can fit the purpose. It comes with 3 pieces - the tube, the plunger, and the cap. The only extra part you would need is a gasket or o-ring with an ID of 0.187" (4.75mm) and OD of 0.35" (8.9-9mm) for the plunger. The one I used was from a Harbor Freight gasket kit (picture shown) and Super Lube was used in this grease tube.
