Building a DIY Arduino 3D printer requires a few key components such as stepper motors, a hotend, a heated bed, and an Arduino board. One can start by assembling the frame using aluminum extrusions or 3D-printed parts. Next, wire the stepper motors to the Arduino board and connect the hotend and heated bed. Then, install the necessary firmware onto the Arduino board and calibrate the printer. Finally, test the printer by sending commands from a computer to ensure it functions correctly. **

The DIY puzzle painted with acrylic colors may be peeling off due to a lack of proper surface preparation before painting. If the surface was not cleaned or primed before painting, the acrylic paint may not adhere properly and start to peel off. Additionally, if the acrylic paint was applied too thickly or in multiple layers without allowing proper drying time in between, it can also lead to peeling. Finally, using low-quality acrylic paint or not sealing the painted surface with a clear varnish or sealant can also cause the paint to peel off. **

Make sure to thoroughly clean and sanitize the wood before using it in the cage to ensure the safety and health of your rats. **
