Coronado SolarMax 60 adapter

I use this adapter with a SkyWatcher 120 ED Pro-Series. The internal diameter is 145mm.

It was very hard to find the right thread dimension, it requires a very precise printing, so i divided it in two parts. Print the internal ring with 0,1 layer height. No need for supports.

The vertical slot on the threads is for z seam aligment, you should specify that slot as custom position to hide the z seam on the thread.

You can print the included knobs to ensure a safe attachment.
