Gravipipe

I saw a video of someone using a covered pipe in a track somewhere that I forget. I was never really able to find the seller or an stl file, so I just fooled around inside Cura until some things connected, coming up with this. NOTE: V1 works best in shortest time to print, as well as marbles inside being visible from the outside, but V2 is much sturdier and takes longer to print. Testing V1 and making a modified and reinforced version of the file, I have no clue if v2 will work perfectly, but I stayed in the boundaries of the previous file to the point that nothing should fail horribly. If something happens, let me know, and I'll make a fix for it. print without supports. That's all from me, if you have any suggestions, let me know! thanks for reading all this! -E
