Theodolite Upgraded Cradle and Bearings

thingiverse

The cradle on wal20's thing was too narrow to accommodate my red dot pointing scope. Also, I had trouble gluing on the pointer and arm and rendered a version with holes in the end to drop in superglue or weep out any potential overflow. The hole in the azimuth pointer plate is smaller in this version so that the rivet nut centers the azimuth plate and clamps the azimuth plate between the tripod head and the hub. **You need to print the pointer plate from [wal20's thing 3714824](https://www.thingiverse.com/thing:3714824)** **You also need to print Theodolit-03-ohne-Support.stl and a mirrored copy from [Mathteacher's thing 2659331](https://www.thingiverse.com/thing:2659331)** Hardware needed to actually assemble this includes 3/8-16 rivet nut. I used a 3/8-16 to 1/4-20 adapter to go on my small tripod head. The screw from my tripod barely reached the nut, but it fit well enough that I did not make a shorter version of the hub bushing. If I were continuing to edit this thing, I would: - Create a pocket in the azimuth pointer to receive the hub bushing. The pocket would only go partway through the plate. - Create a different hub bushing with a longer narrow portion but a shorter total height above base. - Make a small screw assembly process for the cradle attachment, and potentially adapt the vertical parts to be a pillow block design - Add an angle vernier
