Hello,

This is a semi-permanant replacement for the Spooltenna pen, Spooltenna provides to spool your antenna line off and on your spool. This is a modification of Jonathan Kayne's design, which he has posted on Printables.com. The codder pin style modification I've made allows you to remove the spinner hardware more easily than the screw design he came up with. At this time, I don't know if having anything running through the center of the toroid affects the antenna's resonance profile. Being able to remove the spinner in the field is a nice capability if it does affect the resonance profile. I printed mine using a Bambu Labs P1S using Bambu Labs PLA basic filiment.
