Extruder Visualizer Rotation Matrix

This is an extruder visualizer designed for the Original Prusa. It is inspired by a rotation matrix in linear algebra. Attach this visualizer and you'll see a translating rotation matrix! It is for use with two neodymium magnets (φ8×3mm).

Print instructions

Points to note

1. Color change: To change the color of the base plate, letters and arrows, the print file (.gcode) uses the color change function. You can change the color of the letters and arrows by unloading or loading the filament.
   Note: If you want to change the filament automatically using MMU2S, download the data (.3mf) and set up the print settings for the base plate, arrows and letters respectively.
2. Resolution: Letters should be printed in as high resolution as possible. I printed the model with a 0.4mm nozzle, 0.1mm layer height, 0.38mm extrusion width.
3. Ironing: Ironing improves the appearance. However, the letter lines are thin, so if you want ironing, please apply the function only to the base plate and the two arrows.
