Slightly modified version of Rickster434's Minecraft Lever Single Light Switch to allow layer-based color changes. At a .2mm layer height I changed colors prior to layer 68 and layer 73 (double check the specific layers you need to change colors at in your slicer).
1st Color - ZIRO Dark Gray PLA
2nd Color - RepRapper Silk Silver PLA
3rd Color - Sunlu Gray PLA+
The author remixed this model.
Modified the top of the model so not all of the squares are flush and therefore allowing layer-based color changes for those without an AMS printer.
