If using openGrid, print 2x of the openConnect snaps. (Doesn't have to be the ones included, any of the openConnect snaps should work)

If using DDD Wall Control, print 4 of the pins and 1 of everything else.

The iFJF protractor is a different size than the Starrett. 

This is the model I purchased: https://www.amazon.com/dp/B07MX2J9NN

but it doesn't seem to be available anymore. It looks like there are replacements, I'm not sure if they are the same size.
