The drum and the axis pin can be printed in low resolution, with little infill and no supports.
The spinner needs more infill and a high resolution. It might be better to print the spinner in PETG.
I abandoned this project, because I could not get the spinner to last more tham a couple of uses. The tracks are just too thin to not ware out quickly.
The author remixed this model.
I modeled a new drum to fit the SH-6 and used the original spinner of this model.
