Possibly, it is an indispensable accessory to take advantage of the great possibilities offered by current devices, especially if you make public observations and invite people to take their own photograph of the Moon, for example.

It can be attached to eyepieces with an outer diameter of 31 to 45 mm. It supports devices from 73 to 90 mm wide.

In general, the parts do not present great difficulties to print, nor to assemble them. Being a mechanism with guides, small printing defects (including elephant legs) will have to be carefully eliminated to ensure that the parts slide smoothly without gaps, including the holes for the screws.

See in the configuration files how the parts should be placed on the heatbed, to obtain the best surfaces. In particular, the “cruceta” piece must be placed as seen in the image and block all the internal supports, only supporting the sides. It is the key piece of the mechanism.

The "topall mobil" piece requires supports and must be removed carefully. You will need to smooth the surfaces well.

It is advisable to stick a strip of rubber or non-slip material, at least on one of the two sides to prevent the mobile from falling. Adding this material will not be necessary to exert much force to hold the device.
