The file 'Silent Extruder Gears (Rapman) 3D Printer Model' is (stl) file type, size is 271.96 KB.
The standard acrylic involute gears were driving me nuts with their incessant CLICK-CLACK CLICK-CLACK noises, so I designed these herringbone gears to replace them. Now I can't hear my printer from the next room :)
The motor gear has a 'floor' to help you position the grub/nut easily and precisely. The rebate for the nut has also been set back from the shaft a bit to make it easier to fit than ever.
An additional advantage is that they are constantly in mesh, so there is no slack to take up when reversing direction (if you use M227, this happens hundreds/thousands of times each print!) so you will have cleaner prints too.
