This X Y Z axis model was designed for a Physics faculty member. Perfect for classroom sets for students to hold and manipulate. 

I added a version with axis labels as well. Both versions need to be printed with support, and some level of infill is recommended for a good print. 

Pictured versions printed at 100%, .4 nozzle at .20 SPEED settings on Prusa MK 3.9 with 15% infill and grid support from the build plate.
