About this 3D model

These are some small hardware upgrades I designed for the JGAurora A5 3D Printer (Gearbest or Amazon). These quick prints will improve the extruder system my making it easier to disengage the feeding gear and manually feed filament in and out. I attached the button using 3M VHB tape There are two knob designs since my 2 A5 printers shipped with slightly different parts. The gear on the extruder has two tapped holes. If they are 135 degrees apart use V1, if they are 90 degrees apart use V2. See the photo posted with a diagram.
