i think i have finally made the right gear box this is the gear box with all the right stuff finaly has the proper reduction in a simple to assemble box
so now you have a wide range of reductions in my gear boxes to fit just about any nead
the only thing i don't like about this box is that i have reduced the gears thickness back to normal 2mm thickness while it works well i think it will be easily striped but who cares just print another gear ?
cut the pens at
21mm for first set of gears
18mm for the output gears
again use 2mm roofinig 10 guage nails
