Kinetic Extruder Visualizer Engine

thingiverse

Human: Kinetic visualizer pistons for a more actively engaging extruder, inspired by extruder visualizers from other designers. Reciprocating Engine built to attach directly to your dive extruder motor. Can also attach to any motor featuring screw holes in the corners. The engine block is securely held in place by circular tabs that press fit into the standard NEMA 17 stepper motors' screw holes. The fit should be tight so the assembly holds itself firmly in place. If the mounting tabs don't fit your motor, edit the tab size using Thingiverse Customizer. The crankshaft requires a neodymium magnet to hold itself to the stepper motor shaft, with an 8 mm diameter and 3 mm height. Edit: June 26th 2020 Added different cylinder configurations and a customizable propeller. These are not provided as pre-rendered STLs; make them in customizer. Choose from various options: * Single Cylinder * V-Twin * Flat Twin * W Three * Radial Four * Clockwise or Counter Clockwise propeller * 1-8 propeller blades Edit: May 8th 2020 Added Thingiverse Customizer ability! Easily customize the engine to fit your motor right here in Thingiverse. Edit: Feb 16th 2020 Added more versions with tighter tolerances. The original engine was rendered with 0.5 mm tolerances. Now choose between 0.5 mm, 0.4 mm, 0.3 mm, 0.2 mm, and 0.1 mm tolerance. If unsure which one to choose, start with the 0.3 mm tolerance version. Originally, this model was designed in OpenJSCAD. The v-twin.jscad file is now outdated and doesn't contain the new features of engine.scad. To customize the OpenJSCAD engine, load v-twin.jscad into the openjscad.org website and edit the parameters. Then choose an export format and click Generate; after that completes, click Download.
