I made this geometric form in 3D GameStudio from two 3D arches, put together as a group, copied two more times, then turned and twisted them into this geometric form. In 3D GameStudio you can program a lift to move you through the 3D space upwards,forwards, backwards and downwards. I used this geometric thingy in several 3D virtual reality fantasy worlds, with me in third person perspective in the middle of it, moving through the air or through space...
So nice to be able to print it out now too :)

Printed out it also looks nice with the 3D flowers in it!

Made in 3D GameStudio, saved as a Prefab. Converted to 3DS and made into an STL file with Adobe CC Photoshop learning edition. In Photoshop a lot of protective raft was already attached to the object.
In the software of my UP! mini 3D Printer it was printed as an unstable object and was almost totally wrapped in protective raft. However, all the protective raft could be easily removed afterwards.
