Twist Lock Bambu refill spool holder

I don't want to spend 5 hours print the spool holder that came with the printer, so I designed this. It takes a little above 2 hours for printing both pieces, which is about 60% time saving comparing to the model that came with the printer. The holder consists of two parts, P1 and P2, which use a push-and-twist (bayonet) locking mechanism, similar to the original Bambu Lab spool holder.P1 (Main Body)P1 is the larger component and includes the mounting column and alignment index.Insert the refill spool onto P1 first.P2 (Locking Plate)P2 is the flat locking piece. Insert it into P1, then rotate it to the lock position to complete the assembly.
