If one of these goto mounts gets bounced around or knocked over, you stand a good chance of causing this slip nut to break inside the drive unit. Your scope will be virtually useless due to a $2 part that failed. This nut will get you back to enjoying the stars the lazy way.
Part was designed in Tinkercad.
The nut was printed in PLA with a .4 mm nozzle, at .2 mm layer height with a 50% cubic infill. No supports are needed. I chose PLA because if the mount suffers another incident, I would rather have the nut fail rather than damaging the drive train. It was not intended to be the final product, but it worked as is so I left it.
I recommend that you use a .2 mm nozzle and .12 mm layer height for better thread definition. The thread pitch is 1.1 mm.
The nut only goes on one way - top side of your print is the side that needs to be facing up. It can also be a bit finicky to get the nut started. Make sure you clean the threads on the shaft as its a tight fit.
