2-Axis Level Indicator

thingiverse

I crafted this tool as a way to monitor my 3D printer's bed level consistently. To use it, first set up your bed and level it in the standard manner. Next, place the 2-Axis level on the bed and adjust the X and Y screws until the bubbles are perfectly centered. Once you've locked down the screws, simply check the bubble anytime to see if the bed has shifted. If it's still centered, the bed remains unchanged. To use this as a regular 2-Axis level for shelves or other surfaces, just calibrate it on a known flat surface. I designed this in Shapr3D, sliced it with Cura, and printed it using Creality CR-19S Pro with white PLA filament. The holes are threaded for M4 screws, but I opted to drill them out to 5mm and press in threaded inserts in my version. To assemble the small ball pivot, glue it into the hemispheric hole on the arm. This was done to print the arm flat without needing support material, which would have been necessary had the dome-shaped pivot been part of the original model. The spirit level bubbles measure 39.75mm by 9.5mm and were purchased from eBay for a couple of pounds each. I glued them into place using epoxy on a flat surface before adding the pivot ball, ensuring they're inserted relatively horizontally. Finally, glue the ball into its socket and screw in the screws with lock nuts into the holes at the end of the arms.
