Unprofessionally “Fused” the Joiner and Anchor, added some internal fill to make it more solid because it kept breaking. I personally printed it at 75% because I did not want it to break again. You can try it out with whatever infill you want. It worked for me without any modification other than breaking the supports away and taking supports out of the Guard Pin holes (which I eventually had to cut the Guard Pins in order to fit then properly.
The author remixed this model.
