Google Translation of the original model description: First of all, thank you to the author of the original thread model for sharing! Based on the existing idle AMS system, a rotating shaft screw is designed to adapt to the AMS rotating shaft to optimize the original A1 material rack to achieve the purpose of being durable, stable, silent, and avoiding loose consumables. It is very convenient to use it whenever you need to use the AMS system. Notice: 1. The screw file must be printed according to the default placement of the file. It cannot be printed in an upright position to ensure the strength of the screw. 2. It can only be adapted to the green shaft of AMS. 3. The purpose of the two half-ring washers is to make the shaft smoother and quieter during use. Please be sure to print and install it. 4. The original guide bracket needs to be loosened and removed from the side, replaced with the height-increasing adapter bracket in the document and screwed on with the original screws. The adapter frame has a screw hole reserved, which can be locked and fixed with M3*12 self-tapping screws, or it can be installed directly without screws.
