** 2018-10-27 Update ** I got some advice on a french forum. You case use kite string as wire for cool rendering and strength.

** 2018-10-04 Update ** I added small discs to encase the wire/cable that won't go into the winch case.

Hello.

Here's a mini RC winch for a N20 motor.

You'll need two parts from other designers:

The hook: https://www.thingiverse.com/thing:14653

And the gears generated and adapted from janssen86 OpenSCAD library: https://www.thingiverse.com/thing:3134342

It will fit 1/8 until 1/12 models and can be scewed two ways (bottom or back).

The metal parts are:

4 x 50mm m3 screws for the main body 2 x 8mm m3 screws for the front guide

The rope axle is made from a 4mm brass tube which is forced into the 16mm gear. I made a hole through it by pinching a little with a cutting plier and a 1.5mm drill.
