Update.
I modified several things, including the equatorial lever, which I realised was on the wrong side, the diameters of the knobs and the tripod arms, which are now larger and more inclined for greater stability.
Now it should easily support the Seestar S50 as well as the S30.

I have therefore standardised the model for both S30/S50 smart telescopes. Obviously, all light and medium-weight equipment compatible with a 3/8-inch screw can be mounted.
For use with the S50, I recommend using the 2-lobe knob (pomello blocco equatoriale 2 lobi.stl)

This is an equatorial head with polar rotation and spirit level designed specifically for use with the Seestar S30/S50 smart telescope, but it is also perfect for the Dwarf 3 and all light or medium-light units that can be mounted with a 3/8 inch screw.
 
The tripod allows for extremely easy adjustment of the spirit level while keeping the support feet steady thanks to the mounted bearings.
High precision adjustments.

The spirit level allows you to position the tripod ‘optimally’ on any surface, then by adjusting the individual feet it is very easy to bring the S30 or any other device with a spirit level on board to 0.
It is suitable for equatorial inclination values up to approximately 75°

Here is a video showing how to adjust the bubble level. In two minutes, it is perfectly level.

I hope I've included everything

However, you need to thread M3 into the holes in the sides, in the central block, and in the equatorial head to secure the dovetail of the attachment with the 3/8 screw.
You will also need to cut out (or find) a 50 mm diameter piece of felt for the quick release with a 3/8 inch screw
and 3 pieces of felt (or rubber) with a diameter of 20 mm for the support feet.

Material used: PLA, 30% infill, and 0.2 layer thickness.
To print the single-colour version, simply do not load the text and arrows so that the 1 mm depression remains.
