This one took some working to get it to break free. The mojo is capable of printing +\- .007 of an inch so as long as I keep my gaps larger than that it should be fine, however a brain gear I printed had gaps at .009 and I never got it to spin. We were going to print some gears at varying gaps and see what worked but never got to it
BTW: It is interesting that there are almost no review videos of Mojo printer, or most of the other high end desktop printers. Why?
