Anet A6/A3 printhead assembly

thingiverse

I'm making some changes to the hot end assembly of my printer, so I can refine my designs in FreeCAD before printing them out. The STL files that follow are mainly for illustration purposes, except for the acrylic parts which are ready to use as spare parts right away. To help others modify and improve the design, I've included the complete FreeCAD models in two zipped files - one with all components intact and another simplified version that can be easily integrated into other assemblies. The assembly consists of: _Metal parts:_ * Aluminium Sled * Aluminium Heater Block * 0.4mm Nozzle * Teflon Throat Tube & Nut * Extruder MK8 * Fan Grill * Heat-Sink _Electronic parts:_ * Centrifugal Fan, model 5015 * Heat-Sink Fan * Stepper-Motor Nema 17 * Endstop Switch _Acrylic parts:_ * Centrifugal Fan Holder * EndswitchX-Holder _3D printed parts:_ * Fan Duct Each component has been carefully measured on my printer, so there may be differences with other printers. All offsets and misaligned parts are identical to those on my printer. **Edit 04/05/2019:** I've corrected the dimensions of the 5015-Centrifugal Fan and Holder Plate.
