Another Hollow Cube
thingiverse
To remove the base, I opted for Sketchup instead of OpenScad's 'hollow cube' version (as seen in ancestor files). This 30mm cube contains hollow faces and 4mm square bars. It serves various 3D printer tests like ooze/retraction, dimensional accuracy, and squareness, especially bridging. A challenging bridging stage video is available on my blog at numbersixreprap.blogspot.ie/2012/09/bridging-gaps-video-clip-included.html. To print, download the .stl file for a 30mm/4mm cube; alternatively, modify or scale using shared Sketchup files.
With this file you will be able to print Another Hollow Cube with your 3D printer. Click on the button and save the file on your computer to work, edit or customize your design. You can also find more 3D designs for printers on Another Hollow Cube.
