The file 'Lego 48 Tooth Internal Ring Gear 3D Printer Model' is (stl) file type, size is 598.3KB.
really wanted a flat 48 tooth Lego gear, this is Lego compatible and was a great part of my orrery.
works fine for me but it is slightly thicker then normal Lego gears, depending on how you want to use it you might want to reduce the height to 8mm not 9.6mm
files contain a two versions one with teeth only inside and another with teeth on both sides
