This is a tray corner bracket for Tuozhu A1mini (pictured), which can bear a tray weighing at least about 1kg (because I only have a tray of 1ke), and can be printed with PLA filaments, and it will not affect the use within the predictable use weight (PLA is 100% filled, so it affects the printing time),The bracket link is connected to the machine end well, and the tray end can not be inserted to try to heat the bottom surface slightly. I hope it will help you
