Viscous Fluid extruder: Grease Gun
thingiverse
Viscous fluid extruder for main bearings of my 3D printers, I picked up a can of bearing grease and filled the tube completely, it works really well now. I did have to sand the bottom of the pump section so that the tubes fit together properly due to the base of the print being slightly squished, but other than that it worked out great, just make sure you use all the grease in the tube before refilling or a pocket of air gets trapped inside and pushes the ram out of the cylinder. Print Settings Printer: Monoprice III Rafts: No Supports: No Resolution: 0.1 Infill: 100% Notes: Small amount of filing or sanding at the base layer due to improper bed level on my part.
