Epicyclic gear sets DXF STEP Vector files 3D printmodel

What you get will be digital files,it is not a physical product. In the package：
Total 13 external spur gears(pinions) :m1z9,m1z12,m1z15,m1z18,m1z21,m1z24,m1z27,m1z30,m1z33,m1z36，m1z39,m1z42,m1z45,
Total 10 internal and external spur gears:m1z33z44,m1z42z50,m1z54z64,m1z63z73,m1z72z82,m1z75z85,m1z81z92,m1z84z95,m1z90z101，m1z93z104
m1z9-that means the normal module is 1 and the quantity of tooth is 9.
m1z33z44-normal module is 1,quantity of internal teeth is 33 and quantity of external teeth is 44.
You use the parts to assemble at least 10 sets of epicyclic gears that include 3 planetary gears. Any two gears can be assemled as transmission train. STEP and DXF format files are included.
STEP format files can be used on 3d printer;DXF files is for laser cutting or cnc machining.
The parts can be an educational toys for your children.
