I designed an industrial gearbox with two stages:

1. Stage 25 against 15 teeth (i=1,66)

2. Stage 27 against 15 teeth (i=1,8)
 

Overall ratio is 1:3. It has a breather and a maintenance hole on top. It also features an oil drain plug. What you need to purchase in order to make it work are:
 

2x 6004 bearings
2x 6005 bearings
2x NJ 206 bearings

It took me around 22 hrs in total to print with the Bambu Lab X1 Carbon. I recommend to print the shafts with gears in upright position with support. Keep in mind that there are indicators on the first and last stage which should be on top of the print. The housing might need some support, too on the bearing stop rims.
