# Shaft Holder (Screwed Type) ## Basic Shaft Holder A fundamental shaft holder designed for 20mm aluminum frames, providing a solid foundation for spool attachment. ## Modified Shaft Holder An upgraded version of the basic design, tailored to accommodate specific requirements. The distance from the aluminum frame surface to the center of the shaft is extended, offering increased versatility. ## Adjustable Spool Mount A versatile shaft holder that allows for easy adjustment and customization. By specifying the diameter (dd) at the center of the shaft in millimeters, users can ensure a secure fit with their spools. The diameter at the end of the shaft is 5mm larger than this value, requiring a corresponding increase in spool hole size. **Note:** To utilize this design effectively, it's essential to choose a spool width that is smaller than the specified length (ll) of the shaft. This ensures a snug and secure fit, minimizing the risk of spool movement or detachment during operation.
