This can be mitigated by adding double-sided tape to the bottom of the holder, ensuring it stays in place but allowing for easy removal with gentle force. The arm may require adjustment to fit properly onto the driveshaft. It's recommended to use raft support for the arm and print at a slower speed. This design will fit on a 150mm bed. Infill should be set to 20% or higher.
