Free Flight Glider Winch

After watching Maxfliart launch his free flight glider with a modified indoor winder, I was inspired to make a fully 3D printable version.
Google Maxfliart and watch some amazing flying and building videos.
Thanks to janssen86, the gears were generated using his Openscad software:-https://www.thingiverse.com/thing:1587846
The winch has a 10:1 ratio and turning the crank 1 revolution per second produces a good walking pace speed.
The winch so far has not been tested with a glider.
My version was printed on a Fortus 380mc in ABS and as yet I have not printed a PLA version.
Below is the list of items needed to complete the winch, all readily available.

4 Off 10x15x4 Bearings
3 Off 5x10x4 Bearings
