About this 3D model

This is a spool holder corner bracket for Bambu Lab A1 mini (as pictured), which can bear a spool weighing at least about 1kg (because I only have a 1kg spool), and can be printed with PLA filaments. 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 spool end can not be inserted to try to heat the bottom surface slightly. I hope it will help you.
