I already before used a 3D-printed adapter to attache a 90 degree viewer to a Star Adventurer's polar telescope. A big improvement, but still some need to get it better. This time I design my own adapter with the goal to make it much more stable.
Here is my project page with photos and information:

With the indoor test I have done it looks very promising, much more stable now compared to the older one. If the later outdoor tests goes well I will put up STL files for download for you who find it interesting. It fit SkyWatchers EQ6, HEQ5, Star Adventurer polar scopes, maybe others as well.
