Saw a lots of geared spinners in ig, so i decide to make my own.  It uses standard 608zz 8x22x7mm bearings. The tolerances are exact so if it cracks print again with a 1  or 2% increase. Print  settings: Infill: 20% to 100%. It doest really make a difference in the material thats used. Rafts: In the structure, so it sticks well to the bed, its little an it has little addition Supports: No. Have Fun!
