I saw this and just had to have it!! Just waiting on some nice filament so I can get this printed and be mesmerised for a while!
Easy build like all the rest. A bit of a fluctuation in the D hole for motor causing a some wobble. Added a couple layers to top to give a bit more of a hypnotic appearance. Done with a single extruder.
Really like this machine. Works great, and prints real nice. Now if we just had a double wheel it would be that much funner.!!
Unfortunately, I now have to print the connecting parts often and the connections always break off. I'm slowly getting tired of finishing this. With the other marbles there is a stable connection with the screws and these also hold with me. It's a shame, my children were looking forward to it.
Great design, easy to print, lovely to watch
