Thx guys. As soon as I´ve brought the whole room together I will post an Update!
Absolutely fantastic , would you be willing to part with the stl Files?
This Time its not my work because there are so many very good Files out there to print a Vaultdoor, that I`ve just plain used what I found on Thingyverse. In my Case I´ve used a Variant that is suppost to fit for a Lego Vault. The Door is a Bit thick and need a manual adjustment in the splicer Software, but the STL package includes the toothed Rail as well, what most other Vaultdoors Packages do not. For printing I´ve switched to a 0.2mm Nozzle and PETG Filament, what made a better sharpness int he Details!
