Meucci Joint Protector

This joint protector was made for my Meucci cue which I bought somewhere around 2000-2001. 

I have seen things on the web that say a Meucci joint uses a 5/16-18 joint pin and I have printed joint protectors I found that said they were 5/16-18 that were very close but did not fit my cue (maybe it’s slight differences in printer setup / tolerances).

Through trial and error (threads are a real pain in the neck) I came up with this that works for my cue. 

I have printed this in both PETG and ABS and both work fine. I have also printed them on both an A1-Mini and a P1S. 

I’ve added a ‘Test Fitting’ which is just a nut and bolt using the same threads as the joint protector so if you want to test the fit before printing use the test fitting (this basically what I used for the trials and errors).
