Summary Just some simple bar to test printing material strength.. Print a few different materials. Hole in one end to screw down to a table or bench.. over hang 1/2 the bar.,.. then, well.. then break them!! It's fun! LOL Mine were all tested with the basic flat one, but added a tab so others won't need the clamp on the end if trying in a similar way.. https://youtu.be/SVmxMD4WQW4
