The modular bed corners weren't tall enough on my printer. I initially fixed this by printing a 1mm plastic washer. This modified bed corner is more stable.
This model was provided to me in a Lulzbot support ticket.
From Lulzbot Support: I took the bed corners that come with the kit and lowered the portion that interacts with the bed by 0.6mm
Print in TPU/TPE.
The author remixed this model.
