This is a bearing made of double helix planetary gears at an angle of 45 degrees. The solar gear has 32 teeth, the ring gear has 48 teeth, and the planet gears have 8 teeth. The double helix system is used to prevent all the gears from leaving orbit so as to remain centered. The entire design was drawn by me on fusion 360 and there is no tolerance between the parts to be printed as is. It is necessary to set the x/y compensation from the slicer and set the correct distance based on printer accuracy, filament, and the clearance you want to give to the gear. I printed it both in pla and in petg and in abs. On the PETG and ABS print I set an x/y compensation of (-0.05mm), on the pla print I set an x/y compensation of (-0.15mm). I'm attaching some pictures here so you can understand them better. Central to the solar gear is a drive shaft, so that it is strong and robust I recommend setting the wall loop parameter to 10. I set a slight brim to be safe during printing, after printing I recom
