downloaded for review, will probably not use, but wanted to comment that a model design is much more useful if it has the ACTUAL design files, not just the stl.
Hint please to others who post designs here.....
(and thanks Dan for doing that here) (edited)

Great model, settings work well in OpenSCAD. I used it to print out a joint for my central vacuum pipe. Printed in U orientation with generic PLA at 30% infill. Used brim and added supports to the outside and inside of the pipe elbow. (edited)

didnt think to see you here while scrolling through new uploads xD

Have yet to build my makelangelo but i have all the pieces on hand now and will eventually :D
