Lube Applicator

This is my attempt at a minimal lube applicator. I looked at others, but they did not fit my tube of Permatex Grease plus I thought there was a lot of grease filling the void between the tube of lube and the tip of the applicator which would never be recovered. I thought since the requirement to grease the z screw was 3 months I would go for a simplistic design that delivers grease but doesn't have a lot of loss in the application. Also, the applicator takes about 10 minutes to print and can be thrown out after use, so you are not stuck dealing with storing a continuing mess. I have included the step file so you can avoid the issues with different versions of Bambu Studio.
