In light of the recent drop test debacle, we’ve decided on a new infill pattern for the wheel hub. The infill that we used for the drop test was a small square pattern that stays unchanged throughout the print. Evidently, this wasn’t strong enough to handle the stress of the weight of the robot and the impact during the test.
We’ve now printed new hubs with a concentric infill pattern. This makes the print much stronger, and should withstand the next drop test!
How did the new infill work out? Have you done another drop test?
