Holey Grail

This thing is cool thing to see printing and test things. It's either a building block, either a music instrument on its own, either a print test, either something which is something. The first one, I printed it without support and raft on my new stock Ender 3, the print was ok. On my other Ender 3 (with new cheap bed), the adhesion of the external sphere was a trouble, so I added a raft. No raft for testing the printer is cool, but the safest is to add a raft. It's a one block print, the inner sphere is easy to print, but the external brings all the coolish thing : the bottom holes are hard to print correctly, the big surrounding holes are awesome to watch it prints (it's like printing in the void, and challenging your adhesion), and top holes are easy but quite challenging too.. It's 45° angles, it's a prototype but I will add the bar mesh when I'll have all blocks to make an articulated cube / triangle... And maybe it would be cool to make a static cube surrounded by another one... The holes are 1mm bigger than the bar, this allow to add scotch to be safe when building things... or glue it, as you wish..
