This project is solar stystem model. It have all 8 planets and sun, all planets are different size similar to real solar system. Planets can by moved around sun, I made this model with required tolerance to rotate planets, also there is no colisions, so planets can be moved as you want.

Planets are in similar color as real, but i have been limited by my own filament supply so if you want you can change colors or print everything white and than paint planets. For earth and jupiter I used multicolor print to give more detailed model, rest planets are printed in one color, so if you don't have ams you can print using one color per element, but if you want more detailed project you can add details for all planets in Bambu Studio. Model is educational so it musn't be so detailed. Model is small due to bed dimentions limit, but shows diference between planets. Safety lock allow to block movement of planets, push it down to lock them and lift it up a litle bit to allow easier movement.

The longest part of model have around 225mm in xy axis so you are able to print using a1 mini. For a1 mini there is separate print profil. 

I recomend to not change supports in this model because stand arms can float without them and saturn ring can have issues, so it is better to use support. I dont recomend using supports in planets mounting holes, it can couse troubles with removal and assembly. Planets are able to print without support but it is better to use brim. For supports it is the best to use snug type. For better quality of earth is better to use 0,2mm nozle. Model was printed with PLA.

I have got comment that 3 stand ellements have issue during printing on X1C, so I added print profiles with more support, slower speed and slower acceleration. Normal prints are set on default A1 acceleration value and chosing other printer as X1C changes acceleration to default value for this printer, so slower version have locked acceleration and print. It is recommended to use this print profile on faster printers.

Also if you don't have ams there is separate print profile for one color printing per plate.

Assembly is easy but if you have any problems look into documentation. Main things during assembly is correct order of planets stands, after all of them use safety lock. As planets are printed without support, but with brim there is posibility that brim will block posibility of assembly planet with mount, as tolerance is tight that small diference can unable assembly, solution for that is use knife to remove brim from entry of mounting hole, it wil eliminate problem with assembly. It is not required to use glue, but if you want you can use it.

If you will have any issues or sugestions let me know, I can change model a litle bit.
