Marble ferris wheel / fidget spinner

A really fun and easy to print desk toy! Print in PLA or any other stiff material. Print in the orientation of the STL files, no supports needed. Takes less than 2 hours to print for the spinner + stand.  I included a design for the most common marble sizes of 16mm and 14mm. I have used 689 bearings (9x17x5mm), however I created a version for the more common 608 bearing (8x22x7mm) as well! The stand is the same for all versions (bearing size and marble size). Hardware required:  9 M3x8mm bolts (length 5-8mm bolts will work too) 608 or 689 bearing 5 Marbles 14mm or 16mm Find the bearingless version here For marbles 13.5-15.5mm I recommend the 14mm version. For marbles bigger than 15.5mm (but no more than 17) I recommend the 16mm version.
